Abstract:
Newly received or generated paper documents of different content classifications are simply scanned under the control of a digital processor at random in date/time order to produce corresponding electronic images. Each paper document and its electronic image are automatically assigned a unique date/time identifier. No matter how the paper documents are classified, they simply are stacked in sequential folders, which in turn are stacked in sequential boxes. The folders and boxes are marked with the ranges of the date/time identifiers that have been assigned. The digital processor creates records that specify the classifications and the date/time identifiers of the documents. The digital processor then: can provide sets of electronic images that belong to selected content classifications for working purposes, and can indicate the locations of the paper documents in the folders and boxes whenever the need arises.

       BACKGROUND OF THE INVENTION  
         [0002]    1. Field of the Invention  
           [0003]    The present invention relates to systems, processes and products for the storage and retrieval of documentary information, including: physical documents, e.g. paper or photographic documents; corresponding electro-optically generated electronic documents, e.g. digital images produced by scanning or photography; and computer generated electronic documents, e.g. digital text, tables, spreadsheets, etc. produced by word processing, optical character recognition, intelligent document recognition, and/or digital graphics produced by computer aided design.  
           [0004]    2. Description of the Related Art  
           [0005]    Numerous systems and processes have been proposed for the storage and retrieval of documentary information. Traditional practices over the centuries, of course, have involved storage and retrieval by manually accessing indexed arrangements of original papers and other “hard copies” in folders, boxes, shelving and cabinets. Later practices have involved photographically reducing the original papers to produce indexed miniaturizations in microfilm spools or microfiche sheets, storing the spools or sheets in indexed containers, folders or other physical repositories, and retrieving images or hard copies of the miniaturizations by optical projection or photographic reproduction.  
           [0006]    Now there is a proliferation of proposals for digital computer systems that opto-electronically scan original papers or other physical documents to create electronic representations in computer memory, to store digital records of these representations in magnetic and/or optical media, and to retrieve images or hard copies corresponding to these records electro-magnetically or electro-optically. It is common experience that effective paper filing systems have required unerring care by trustworthy persons who have some understanding of the business or other activity involved. Considerable reliance often has been placed on the memory of such persons, who have a tendency to become “indispensable” in mission critical situations. Moreover, even a generally effective system often is not conducive to physical and logical arrangements capable of implementing prompt storage and retrieval without constant inquiries to and guidance by professional level personnel. Finally, of course, a paper file is available to only one person at a time unless hard copies are made, in which case undesired paper proliferation occurs.  
           [0007]    Although a few, but not all, of these problems are alleviated by the use of microfilm and microfiche, new and different problems arise. It is true that a large number of photographic miniaturizations can be stored in a much smaller space than an equivalent number of original papers. However, problems of storing and retrieving containers and folders of microfilm and microfiche are not unlike problems of storing and retrieving batches of their paper counterparts. More important, producing, imaging and retrieving photographic miniaturizations often are costly procedures requiring unwieldy hardware. As a practical matter, microfilm and microfiche may be limited to archival-type documentation that may not be compatible with a dynamic work environment.  
           [0008]    Modern advances in low cost computer architecture, particularly, faster clock speeds, higher resolution displays, and denser storage media, have generated discussions of whether or not a “paperless office” is possible, and, indeed, what is the meaning of “paperless office”. The difficulties mentioned above in connection with the storage and retrieval of paper documents, in a work environment, make it clear that minimization of the use of paper must be a preeminent practical objective. A critical advantage of electronic files over paper, microfilm, and microfiche files is that electronic files can be readily stored, sorted, retrieved and reorganized.  
           [0009]    It is apparent that electronic files are capable of obviating tedious manipulation of original paper files when there may be no further need ever to refer to them. Nevertheless, despite the rapid growth of electronic filing, paper documents continue to proliferate. In many cases, reference to papers or other original physical documents, even if infrequent, may be essential. For example, original physical documents may be required or desired: (1) in litigation where particular rules of evidence may pertain; (2) as backup in the event that lost or faulty electronic images are discovered later; (3) in major commercial, financial and insurance dealings where physical signatures may be important or merely may be perceived to be important; (4) in internet transactions where the parties do not meet legal requirements for dispensing with paper signatures; (5) as backup for technical graphics, precision photographs, medical diagnostics, and the like, where differences in resolution between images and originals may become critical; (6) as backup in the event of corruption of electronic files; and (7) as complete copies of voluminous treatises in which only the table of contents and/or other selected portions may be imaged as a matter of convenience.  
           [0010]    Another very possible reason for the continued proliferation of paper is a natural reluctance on the part of many to discard original paper files even after they have been imaged and stored in electronic media. For many, it simply may be difficult to overcome a habitual predilection to keep paper documents, and to accept the idea that electronic media, in many cases, is a secure and relatively versatile substitute. For many others, some types of paper documents, much of the time, simply are more comfortable to use, e.g. books, periodicals, etc.  
           [0011]    Modern society demands knowledge work that is appropriate for the information age. The requirements are that: relatively low paying manual work, like filing paper documents, must be phased out; and relatively high paying knowledge work, like processing electronic documents, must be phased in. The fact is that total elimination of paper documents may be unachievable and/or undesirable. Rather, the present invention is based on clearly recognizing that there is an optimal interaction, in every commercial and technical situation, between minimizing the inherent inefficiency of storing and indexing paper documents, and maximizing the inherent efficiency of storing and indexing electronic documents.  
           [0012]    Much confusion has been encountered in implementing systems that are based on: (1) imaged electronic documents of the type that are created by scanning or photographing paper documents and the like, (2) original paper documents themselves, and (3) computer generated electronic documents of the type that are created by word processing or graphics programs, e-mail or facsimile transmissions, and the like. The following are some of the conflicts involved: whether to store bit maps based on simple scanning, or text resulting from optical character recognition, or both; whether to mix optically generated electronic documents and computer generated electronic documents; to what extent the storage of optically generated electronic image files should mirror the storage of the original paper documents; whether or not an original paper filing system should be retained without change; whether or not a system is so sophisticated that computer literate professional level operators and/or supervisors are required; and whether or not a system is so rudimentary that even entry level operators may be sufficiently trustworthy.  
           [0013]    The foregoing problems are greatly magnified (1) in systems dealing with law, medicine, finance, insurance, engineering and other disciplines, where difficulties may be encountered in retaining specifically knowledgeable personnel, and (2) in networked systems, where difficulties may be encountered particularly in standardizing procedures for the physical storage and retrieval of original physical paper documents, and, possibly, hard paper copies of electro-optically generated and computer generated documents, at disparate locations.  
           [0014]    There is a requirement for systems in which the physical filing of paper documents is radically simplified, in which access to the locations of infrequently needed paper documents is precisely indicated, and in which optically generated electronic documents and computer generated electronic documents are clearly differentiated.  
         DEFINITIONS  
         [0015]    In order to maintain clarity, the present document adopts the following definitions:  
           [0016]    (I) physical documents (sometimes abbreviated to physical files) are defined herein as actual paper documents or actual photographs or the like, of the type that are manually tangible and visually perceptible;  
           [0017]    (II) electronic image documents (sometimes abbreviated to image documents or image files) are defined herein as electronic files of the type that are generated electro-optically by scanning or photographing physical documents such as actual paper documents, photographs, and the like. In one form, these electronic image documents are bitmap documents;  
           [0018]    (III) electronic work documents (sometimes abbreviated to work documents or work files) are defined herein as electronic documents that are generated in a computer by a word processor program, a spreadsheet, a computer aided design program, e-mail, facsimile, or the like. These electronic work documents may be in such formats as “pdf” (portable digital format) such as that sold by Adobe Systems, Inc., or as XML (Extensible Markup Language) such as that being adopted by Microsoft Corporation and others.  
           [0019]    (IV) electronic documents (sometimes referred to as electronic files) include electronic image documents and electronic work documents.  
         BRIEF SUMMARY OF THE INVENTION  
         [0020]    The primary object of the present invention is to provide, for the storage and retrieval of physical documents, electro-optically generated electronic documents, and computer generated electronic documents: systems, processes and products, which facilitate the use of electronic documents rather than physical documents whenever feasible or acceptable, and which facilitate the use of physical documents rather than electronic documents whenever necessary or preferred. The result is less individual and organizational frustration, and more creative use of time.  
           [0021]    Pursuant to the present invention, at any isolated location or at any one or more locations in an enterprise comprising a network or group of networks: (1) newly received or generated electronic documents are simply entered at random in a sequence of date/time instances by computer generation and/or by electro-optical processing of physical documents; (2) the records of the electronic documents reference the date/time instances that constitute unique identifiers; (3) each of the physical documents is added to the beginning or the end of a cumulative stack in which its location is indicated by its date/time instance; and (4) the electronic documents are processed and organized to provide the electronic equivalent of virtual files that include related physical and electronic documents.  
           [0022]    A preferred embodiment of the present invention includes a physical system and an electronic system. The physical system is characterized by a primary physical repository and a plurality of secondary physical repositories therein or thereon, which hold selected sequences of physical documents corresponding to selected ranges of the date/time instances. The selected ranges of the sequences of physical documents are contained by selected ones of the secondary physical repositories. The selected ones of the secondary physical repositories are visually marked with physical indicia corresponding to the selected ranges of the date/time instances. The electronic system is characterized by electronic tables, each representing a grid containing rows of electronic records and columns of electronic fields, the electronic fields including a plurality of primary (or ONE or key) electronic fields, and a plurality of secondary (or MANY or non-key) electronic fields. One of the primary fields includes date/time entries that uniquely designate corresponding logical groups of physical documents and corresponding logical groups of electronic documents. These date/time entries designate the precise physical locations of the corresponding physical documents. The secondary fields include other entries that designate other corresponding logical groups of physical documents and electronic documents. Such other groups of physical documents, in effect, are virtual groups of physical documents.  
           [0023]    The result is an interactive combination of electronic records, which specify the precise physical locations of selected physical documents in terms of their date/time instances. Thus, selected logical groups of physical documents are virtual collections that are intermingled throughout the secondary repositories in a manner that does not permit them to be immediately available for physical compilation. On the other hand, such virtual collections correspond to selected logical groups of electronic images that are immediately available for electronic compilation and presentation.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS  
       [0063]    The Physical and Electronic Systems of FIGS.  1  to  6   
         [0064]    As shown in FIGS. 1 and 1 a,  the illustrated embodiment of the present invention comprises a master system that includes a physical system  30  and an electronic system  32 . These systems share an electro-optical scanner or camera  34 . Scanner or camera  34  processes random sequences of physical paper documents  36  to produce sequences of electronic image documents  56  in sequences of date/time instances.  
         [0065]    Sequences of paper or plastic depositories in the form of file folders (or file pockets)  38  in turn store the sequences of paper documents  36 . As is shown in FIG. 5, each of folders  38  is marked with indicia  40 ,  42 , which indicate the beginning and ending of the range of date/time instances of the paper documents there within. Sequences of depositories in the form of cardboard or plastic boxes  44  store the sequences of folders  38 . As is shown in FIG. 6, each of boxes  44  is marked with indicia  46 ,  48 , which indicate the beginning and ending of the range of date/time instances of the folders there within.  
         [0066]    Electronic system  32  includes a computer workstation  50  that is operatively connected to scanner  34  for transmission to the scanner of control signals, and receipt from the scanner of data signals representing image documents and their unique date/time instance identifiers. Workstation  50  controls the production by scanner  34  of electronic image documents  56 , e.g. vector and bitmap images, and generates electronic work documents  57 , e.g. from text and graphics programs, or from e-mail or facsimile transmissions. Electronic image documents  56  and electronic work documents  57  are grouped as electronic documents  59 .  
         [0067]    Workstation  50  controls a printer  52  for producing labels as in FIGS.  4 , and transmits digital information, including the date/time instances of their creation, for recording in a database in an electronic storage  54 . Electronic storage  54  typically takes the form of magnetic, optical, or magneto-optical media, e.g. disks or tape. As shown in FIGS. 2 and 3, workstation  50  can present the image documents generated by scanner  34  as thumbnail views  56  or blow-up views  58 .  
         [0068]    As shown in FIG. 1, physical system  30  includes a plurality of shelves  60 . Stored on these shelves are boxes  44  (and/or other bundles), which contain folders  38  (and/or other physical repositories). As stated previously in connection with FIGS. 4, 5, and  6 , each of the boxes  44  in FIG. 1 is marked with indicia  46 ,  48 , which indicate the beginning and ending of the range of date/time instances of the folders there within.  
         [0069]    Preferably, indicia  40 ,  42 ,  46 , and  48  are presented in both date/time alphanumeric characters and date/time bar code. In an alternative embodiment, these indicia are presented in other alphanumeric characters and/or other bar codes that indirectly refer to date/time instances. The arrangement is such that any of the boxes themselves, or any of the folders they contain are available for convenient visual or optical retrieval. Furthermore, any of the papers there within are available for convenient visual and manual retrieval because of the relatively isolated short stacks in which they are confined.  
         [0070]    The Relational Database of FIGS.  7  to  11   
         [0071]    Electronic system  32  provides and controls a relational database  61 , which includes: an Entity Code Table  62  as shown in FIGS. 7 and 7 a;  a Document Entry Table  64  as shown in FIGS. 8 and 8 a;  a File Table  66  as shown in FIGS. 9 and 9 a;  and a Task Table  68  as shown in FIGS. 10 and 10 a.    
         [0072]    The Entity Code Table, which is shown at  62  in FIG. 7 and described in  7   a,  includes a Main_Code_ID field, which identifies each entity in the database by a unique code, and a Main_Code_Class field, which characterizes each such entity as an organization or individual. A preferred code, which is not novel per se, comprises as values either of the following. (1) In the case of an organization, the code consists of the first five alphanumeric characters of a company name plus a successive integer beginning with 001. (2) In the case of an individual, the code consists of the first five alphanumeric characters of the individual&#39;s surname plus a successive integer beginning with 001. The successive integer serves to distinguish codes of companies and individuals that are otherwise the same. The Entity Code Table also includes a Related_Code_ID field, which may identify a secondary selection from the Main_Code_ID, and a Related_Code_Class field, which may indicate one of a class of relationships, i.e. contact, officer, adversary, etc., between the Main_Code_ID field and the Related_Code_ID field.  
         [0073]    The Document Entry Table, which is shown at  64  in FIG. 8 and described in FIG. 8 a,  includes a Doc_Entry_Date_Time field, which contains Date_Time values that uniquely identify the electro-optical or computer-generated presentations, i.e. values, in the Doc_View field. Preferably, a unique value in the Doc_Entry_Date_Time field is generated automatically by the system during scanning or computer generation, preferably in terms of year, month, day, hour, minute and second (yy, mm, dd, hh, nn, ss). As a practical matter, a duplicate automatically generated value in the date/time field is precluded in many server systems since any slight automatic delay will cause the generation of a second nonduplicate value. Thus each electro-optically generated document or computer-generated document is uniquely identified at the moment of its creation by a date/time entry. The data type of the Doc_View field is any electronic document, i.e. data object, that is supported by the electronic system, whether image, text, vector or bit map.  
         [0074]    The File Table, which is shown at  66  in FIG. 9 and described in FIG. 9 a,  includes a File_Name field, each value of which is a unique identifier of a particular class or category, and an Official_No field, which, for example, may refer to a government agency serial number or registration number, a court docket number, a medical plan or group number, an insurance policy number, a retail or wholesale customer number, a law practice client number, a medical practice patient number, or the like. Pursuant to the present invention, physical documents of different entities, which may be classified in any such File_Name or Official_No field, are randomly dispersed throughout the primary and secondary repositories of physical system  30 .  
         [0075]    The Task Table, which is shown at  67  in FIG. 10 and described in FIG. 10 a,  includes: a Main_Code_ID field, which typically refers to a value that is indexed in the Main_Code_ID field of Entity Code Table  62 ; an Our-File_No field, which typically refers to a value that is indexed in the File_Name field of File Table  66 ; and a Designated_Rep field, which typically indicates the person responsible for performing any required task as referenced in a value that is indexed in the Main_Code_ID field of Entity Code Table  62 .  
         [0076]    As shown in FIG. 11, the following relational links exist among the tables of the illustrated relational database. The Main_Code_ID of the Entity-Code Table is linked to the Main_Code_ID fields of the Doc Entry Table and the Task Table. The Our_File_No field of the File Table is linked to the Our_File_No fields of the Doc Entry Table and the Task Table. The arrangement is such that the specific location of any physical document is available to any person classified in the Designated Rep field of the Task Table, no matter who is the person who entered the physical document in the system.  
         [0077]    The Query of FIGS. 12 and 13  
         [0078]    FIGS.  12  shows a Query Table  68  and FIG. 13 shows a computer having a graphical user interface  70 , which demonstrate the retrieval, from an electronic form  72 , of an electronic document  74  and the precise physical location  76  of the corresponding physical document.  
         [0079]    The Physical and Electronic Systems of FIGS.  14  TO  16   
         [0080]    [0080]FIG. 14 shows a master system that includes a physical system  80  and an electronic system  82 . These systems are associated with a relational database configuration of the type shown in FIGS.  7  to  11 . The physical and electronic systems share a scanner  84  and a printer  86 .  
         [0081]    Scanner  84  processes random sequences of paper documents  88   a  and  88   b  to produce sequences of electronic image documents in sequences of date/time instances. Printer  86  produces physical visual indicia that show the start and finish of any such sequence of date/time instances. As will be explained in greater detail below, physical system  80  processes two physical document streams  88   a  and  88   b.  Sequences of physical documents of the first physical document stream  88   a  are archived permanently. Sequences of physical documents of the second physical document stream  88   b  are archived for a limited term or terms.  
         [0082]    In first physical document stream  88   a,  sequences of physical folders  92   a  store sequences of paper documents  88   a  from the scanner, and sequences of boxes  94   a  in turn store the sequences of folders  92   a.  In second document stream  88   b,  sequences of physical folders  92   b  store sequences of paper documents  88   b  from the scanner, and sequences of boxes  94   b  in turn store the sequences of physical folders  92   b.  The destination of folders  92   a  and boxes  94   a  is physical Location A at  104   a.  The destination of folders  92   b  and boxes  94   b  is Location B at  104   b.  The physical folders and boxes typically are constructed from inexpensive materials, composed, for example, of cardboard, plastic or the like.  
         [0083]    As is shown in FIGS.  15 , the physical visual indicia for the folders and boxes of the first physical stream are respectively in the form of pressure sensitive labels  96   a  and  98   a,  which respectively are mounted on the release plastic coated faces of carrier sheets  100   a  and  102   a,  respectively. When labels  96   a  and  98   a  are peeled from carrier sheets  100   a  and  102   a  and applied to folders  92   a  and boxes  94   a,  respectively, the printed indicia indicate the start and finish of the range of date/time instances of the paper documents there within, and additionally the physical destination, location A, of the relevant document stream. Similarly, when labels  96   b  and  98   b  are peeled from carrier sheets  100   b  and  102   b  and applied to folders  92   b  and boxes  94   b,  respectively, the printed indicia indicate the start and finish of the range of date/time instances of the paper documents there within, and additionally the physical destination, location B, of the relevant document stream  
         [0084]    As shown in FIG. 14, distinguishably marked boxes  94   a  and  94   b,  are stored on shelves  104   a  and  104   b  in physical locations A and B, respectively. Location A receives those physical documents that are to be archived permanently, and location B receives those documents that are to be archived for a limited term that ends on a date certain.  
         [0085]    Electronic system  82  includes a workstation  106  and an electronic storage  108  that contains a relational database  109 . Workstation  106  is operatively connected to scanner  84  for transmission to the scanner of control signals that synchronize the generation of date/time instances, and that receive from the scanner data signals representing electronic image documents and their date/time identifiers.  
         [0086]    As indicated earlier, workstation  106  also generates electronic work documents  107  other than electronic image documents, i.e. those produced by word processing or computer aided design, or those received by transmission from local area or wide area networks, facsimile, or the Internet. All such electronic work documents, like all of the aforementioned electronic image documents, are uniquely identified by date/time instances that are assigned at the time of their production by computer generation, transmission or reception. These electronic image documents and electronic work documents are collectively shown as electronic documents  111 .  
         [0087]    Workstation  106  is operatively connected to electronic storage  108  for transmission to and retrieval from storage  108  of control and data signals that represent electronic image documents and electronic work documents, and their date/time identifiers. These electronic documents are image documents and work documents in any of various bitmap, vector, text or other formats, such as the PDF (Portable Document Format) format promulgated by Adobe Systems, Inc., or the XML (Extensible Markup Language) format promulgated by Microsoft Corporation among others.  
         [0088]    In the manner shown in FIGS. 2 and 3, workstation  106  can present the electronic image documents and the electronic work documents as thumbnail views or blow-up views. Workstation  106  is operatively connected to printer  86  for transmission to and receipt from the printer of control signals for the production of physical documents. These physical documents include labels  96   a,    98   a,    96   b,  and  98   b,  as well as read-outs of logical sets of records that are retrieved from electronic storage  108 .  
         [0089]    The Query of FIGS. 17 and 18  
         [0090]    [0090]FIG. 17 shows a Query Table  110  and FIG. 18 shows a computer having a graphical user interface  112 , which demonstrate the retrieval, from an electronic form  114 , of an electronic document  116  and the precise physical location  118  of a corresponding physical document.  
         [0091]    The Physical and Electronic Systems of FIGS.  19  TO  22   
         [0092]    [0092]FIG. 19 illustrates an enterprise system that comprises: a plurality of local area networks  120 ,  122 ,  124 , and a master network  126 . Local area networks  120 ,  122 , and  124  are physical accounts that are at different physical locations C, D, and E. Master network  126  is at a central physical location Y. Each of the local networks includes a local physical system  128  and a local electronic system  130 . The master network includes a master physical system  132  and a master electronic system  134 . These systems are associated with and have access to a relational database configuration of the type shown in FIGS.  7  to  11 . Preferably, this relational database configuration resides in master electronic system  134 .  
         [0093]    Physical system  128  and electronic system  130  share a scanner  136  for processing random sequences of paper documents  138  to produce sequences of electronic image documents in sequences of date/time instances. Sequences of paper or plastic folders  140  in turn store the sequences of paper documents. Each of folders  140  is marked with indicia  142 ,  144 , which indicate the beginning and ending of the range of date/time instances of the paper documents there within, and additionally the physical location  146  of the relevant physical account. Sequences of cardboard or plastic boxes  148  store the sequences of folders  140 . Each of boxes  148  is marked with indicia  150 ,  152 , which indicate the beginning and ending of the range of date/time instances of the folders there within, and additionally the physical location  154  of the relevant physical account. Full boxes  148  are transported to a central physical location  156 , which is designated as Location Y in FIG. 19.  
         [0094]    Electronic system  130  includes a file server  158  that is operatively connected to scanner  136  for transmission to the scanner of control signals, and receipt from the scanner of data signals representing image documents and their unique date/time instance identifiers. A plurality of workstations  160  are operatively connected to server  158  via a hub  162 . Workstations  160  can call up electronic documents, including electronic image documents, from server  158 , and can generate electronic work documents, including text, vector and bitmap documents for transmission to server  158  and recording in terms of the date/time instances of their creation. Server  158  in turn is operatively connected to a bridge  164  for further processing of its electronic image and computer generated documents. In the manner shown in FIGS. 2 and 3, workstations  160  can present, as thumbnail views or blow-up views, the electronic image documents generated by scanner  136  and the electronic work documents generated by workstations  160 .  
         [0095]    Physical system  132  of master network  126  includes one or more off-site depositories  132 , each of which includes a plurality of shelves  166 . Stored on the shelves are boxes  148  and/or other bundles, which contain folders  140  and/or other physical objects. In the manner described earlier, each of folders  140  is marked with indicia  142 ,  144 , which indicate the beginning and ending of the range of date/time instances of the physical documents therewithin. As stated previously, each of boxes  148  is marked with indicia  150 ,  152 , which indicate the beginning and ending of the range of date/time instances of the folders there within, and an indicium  154 , which indicates the location of the account from which the box was physically shipped.  
         [0096]    Preferably, indicia  142 ,  144 ,  146 ,  150 ,  152  and  154  are presented in both date/time alphanumeric characters and date/time bar code. In an alternative embodiment, these indicia are presented in other alphanumeric characters and/or other bar codes that indirectly refer to date/time instances. The arrangement is such that any of the boxes themselves, or any of the folders they contain are available for convenient retrieval.  
         [0097]    [0097]FIGS. 21 and 22 illustrate the labels that are applied respectively to the folders and boxes of physical accounts  122  and  124  to visually present their ranges of date/time instances. The boxes of physical accounts  120 ,  122 , and  124  all stored in the order of their initial date/time instances. In effect, boxes from all of Locations A, B and C are intermingled with each other, but are sequenced in the order of their initial date/time instances.  
         [0098]    Electronic system  134  includes a database server  168 , which is operatively connected to a bridge  170 . Bridge  170  in turn is operatively connected to the bridges  164  of local networks  120 ,  122 , and  124 , at C, D, and E, respectively. Server  168  also is operatively connected to a master electronic storage  172 , which is the central electronic repository of all relevant image generated electronic documents and all relevant computer generated electronic documents in the illustrated enterprise system. Electronic system  134  provides and controls a relational database of the type shown in FIGS. 7 through 11.  
         [0099]    Preferably, a value in the date/time field of the Document Entry Table is automatically generated by the system during scanning or computer generation, preferably in terms of year, month, day, hour, minute and second (yy, mm, dd, hh, nn, ss). Thus each electro-optically generated image document and each computer generated work document is uniquely identified at the moment of its creation by a date/time entry.  
         [0100]    The Query of FIGS. 23 and 24  
         [0101]    [0101]FIG. 23 shows a Query Table  172  and FIG. 24 shows a graphical user interface  174 , which demonstrate the retrieval, from an electronic form  176 , of an electronic document  178  and the precise location  180  of a corresponding physical document.  
         [0102]    Practical Choices of Physical Repositories—FIGS.  25 - 31   
         [0103]    The physical repositories of the present invention may take various forms. Their choice involves a trade-off among security, cost, and convenience. A folder consisting simply of two flaps is low in cost and convenient to use for the reception of a limited batch of loose random paper documents. However, filling and stacking a series of such folders in a box or other secondary repository, or retrieving such a folder from a box of such folders, as a practical matter, may not provide sufficient security to maintain the integrity of a loose stream of important documents, particularly if not handled with relative care. For greater security but higher cost, it may desirable to provide a depository in the form of a pocket, which totally encompasses the bottom and sides of a sequence of randomly inserted papers, and a cover to provide a complete enclosure. However, it has been found convenient to omit the cover in order to simplify initial insertion and possible later retrieval of a limited batch of loose random documents, particularly when the pocket is one of many stacked in a box with a cover. There follow two implementations.  
         [0104]    One preferred physical system incorporates a particular type of file pocket, which is well known in the art, but which is modest in cost compared to many other file pocket types. This preferred file pocket is shown in FIGS. 25 through 29. This file pocket has a back panel  182 , a front panel  184 , a pair of inwardly directed side gussets  186 ,  188 , and a bottom gusset  190 . Each side gusset includes a first fold  192 , which continues inwardly from back panel  182 , a second fold  194  which continues outwardly from the first fold, and a third fold  196 , which continues inwardly from the second fold and is cemented to front panel  184 . Folds  192  and  194  are joined by an inward crease  198  that is parallel to the adjacent side edges of the front and rear panels. Bottom gusset  190  includes a first fold  200  that continues forwardly from back panel  182  and a second fold  202  that continues rearward from front panel  184 , the two folds being joined along an inward crease  204  that is parallel to the adjacent bottom edges of the front and rear panels. The opposite ends of bottom gusset  190  have V-shaped cutouts  206  and  208  that accommodate the lower ends of side gussets  186 ,  188 . All of these features are stamped and configured from an integral blank sheet of thin cardboard. In use, these file pockets merely need be stacked in a box or on a shelf with minimal concern about loss of documents from batches of documents therein.  
         [0105]    Another system, which is available where low cost is important and security may not be critical, is shown in FIGS. 30 and 31. The physical sub-system comprises simple stacks or batches  210  of papers that are in the order of the date/time sequence of their electro-optical and/or computer generated creation. For convenience, these stacks or batches are separated by dividers such as slip sheets  212 , or containers such as simple envelopes (not shown), into sequential date/time intervals. Since the precise location of any original is indicated by its date/time instance, its manual or machine accessibility is immediate and unambiguous. Each of the designated stacks is physically assigned a date/time interval, and each of the included images is electronically assigned a date/time entry within that interval.  
         [0106]    The integrity of any designated stack is maintained by monitoring the physical storage and retrieval of any processed document to and from that stack. The operation is such that scanning a series of randomly collected documents produces, interactively in real time, physical stacks of the processed documents and electronic groups of corresponding images and other electronic documents.  
         [0107]    In the illustrated embodiment, the physical documents of each batch are stacked from bottom-to-top or rear-to-front. The batches are separated by slip sheets, the foremost one of which is marked with visual indicia that specify at least a date/time instance that is no earlier than the foremost paper document in the date/time interval that it delineates. Thus, each batch is physically located in a physical repository that is located between a pair of slip sheets. Each of the electronic documents is identified by electronic indicia of a date/time entry within that interval. After a batch is removed from its sequence of batches for review, as at 222, it may be replaced at the front of the sequence, as at 224. In this case, the slip sheet is marked with the date of the replacement and the electronic documents corresponding to the relevant physical documents are designated with additional indicia that reflect the change in physical location.  
         [0108]    In an alternative embodiment, physical documents of each batch are stacked from top-to-bottom or front-to-rear. The batches are separated by slip sheets, the rearmost one of which is marked with visual indicia that specify at least a date/time instance that is no later than the rearmost paper document in the date/time interval that it delineates. Each of the electronic documents is identified by electronic indicia of a date/time entry within that interval. After a batch is removed from its sequence of batches for review, it may be replaced at the end of the sequence. In this case, the slip sheet is marked with the date of the replacement and the electronic documents corresponding to the relevant physical documents are designated with additional indicia that reflect the change in physical location.  
       OPERATION  
       [0109]    Pursuant to the present invention, at each geographical location: (1) electro-optically generated electronic documents are produced by scanning newly received paper documents at random, and computer generated electronic documents are produced at the distributed work stations or the distributed servers by newly received fax or e-mail documents, all in date/time sequence; (2) any original paper or other hard documents to be saved are stored in date/time sequence, and (3) the images are processed and organized to provide the electronic equivalent of organized files of paper documents. The result is an interactive combination of electronic and physical sub-systems that operate in the following manner. The physical documents are arranged in batches that are stacked in the secondary depositories, i.e. folders and boxes. Each of the batches of hard documents corresponds to a limited range of successive date/time instances and each of the secondary depositories is marked with visual indicia matching this limited range. Scattered through the various batches of hard documents are selected hard documents that are related logically by selected indicia other than date/time. The master electronic system computes and retrieves requested subsets of the electronic images corresponding to these selected hard documents.  
         [0110]    Electronic image documents and electronic work documents are acquired or produced to provide one or more real time sequences of electronic documents in one or more real time sequences of date/time instances. Acquired or produced physical documents simply are added to the front (or the back) of one or more cumulative physical stacks. The resulting electronic records uniquely identify the physical locations of the physical documents and the electronic locations of the electronic documents, both in terms of their associated date/time instances. These date/time instances guarantee that virtual sets of related physical documents may be readily located and conveniently retrieved, and that corresponding sets of related electronic documents may be immediately displayed and suitably reported. Pursuant to any particular archive policy, these date/time instances guarantee the joint destruction of corresponding physical and electronic documents that have been received and/or created prior to any selected date.
