Abstract:
A blank book attachment having a mark and sweep leaf with a fold out feature is provided. The leaf is pivotably retained along one edge on a frame, and the frame is pivotably retained at the binding spine of the host blank book. Pulling outward on the leaf causes the leaf to extend out and beyond the pages of the book allowing the pages to turn freely. When the leaf is placed within the host book, with the book open or closed, the leaf can be turned as a page, in which case it also acts as a mark to identify a specific position in the host book. Alternatively, the leaf may be pivoted on the frame to allow the host book pages to be turned past it in either direction.

This is a continuation of application Ser. No. 324,417, filed Mar. 16, 1989. 
    
    
     BACKGROUND OF THE INVENTION 
     This invention relates to &#34;host blank books&#34; with a fixed or variable number of pages including spiral bound note books, multi-ring bound books, staple-, tape-, or glue-bound books, plastic finger clasp bound books, and the like, add-in leaves in the form of mounting surfaces with additional pages, and particularly, a repositionable mounting surface with a fold-out feature. 
     Host books are typically sold in a variety of forms including glue- or tape-bound with cover, staple-bound with cover, spiral-bound with cover, and ring-bound with cover. They may have a fixed or variable number of pages or no pages, and the pages may be blank pages, pages with text or pictures, where the text may be formatted or unformatted. Typically, host books with pages that are intended for writing or which contain text and or pictures in any form do not easily allow for the insertion of notes, except for use of margins, specially identified format blocks, or spaces between lines or pictures. Arbitrary notes must be taken on loose pages which themselves can be retained in the host book in a variety of ways as marks. Host pages that have pre-defined formats support structured entry of information but often do not support arbitrary input or output notes very well. 
     Host books have pages which are typically bound in a sequential order. If the pages can be repositioned, it requires opening of the binding and the removal and reinsertion of the pages to be repositioned. Tagging these pages or marking them for reentry requires (a) folding the page, (b) placing a loose mark in the page which could fall out, or (c) binding a mark that attaches to the page and stays on the page unless physically removed and replaced at another point. Noting or marking in this way either damages the book or covers the written material. Additionally, this type of marking does not easily allow for the continuous collection of information on the mark as the mark is moved through successive pages. 
     Electronic, computer-based text has been developed which can be accessed on-line via a personal computer or through a shared information utility and which addresses the issue of flexible information manipulation. The basic technology is known as hypermedia, and specifically, as it relates to textual information, hypertext. This capability provides the individual the ability to attach new information to any context he or she is working with, and to view that portion or chunk of specially tagged information out of context from its location in relation to other such specially tagged information, or in context with its location in the body of the text. In this sense, &#34;hyper-access&#34; means that one may view the tagged information dynamically out of context as well as in relationship to the source item or items. The mechanism provided for viewing information on the computer is known as &#34;multiple-windowing&#34;. This feature has proven very powerful and has opened up entirely new applications for computers in desktop publishing, computer-aided design, project management, and the like. 
     This capability has been unavailable to users of blank books due to the inherent limitation of physically bound surfaces and their supporting bindings. 
     SUMMARY OF THE INVENTION 
     The invention, therefore, relates to frames, leaves, additional pages for a blank book, fold-out surfaces, and particularly to book marking and more particularly to a special purpose binding that offers dynamic book marking with a fold-out mounting surface capable of supporting additional foldable surfaces. 
     The invention is a special purpose binding which can be attached to a host book in a variety of ways, and which offers the arbitrary placement of a single surface or a set of surfaces such that each independent surface positions to insert itself within the host book or alongside the host book while remaining attached to the host at all times. 
     The invention further relates to special bindings that offer &#34;hyper-extending&#34; frames that provide a mechanical analog of a hypertext system and in this manner offer the facility of a new page for a blank book that can &#34;float&#34; from context to context within the book and be viewed independently of any page of the book, in sequence with any page of the book, or at the same time as any page of the book, while retaining an attachment to the book. 
     It is the object of this invention to provide a form of &#34;mechanical hypertext system&#34; which provides a repositionable surface with a plurality of folding surfaces on it. The plurality of surfaces, viewed as floating pages, behave as pages of the blank book when positioned within the host book, turning as would the pages of the enclosing book. The floating surface then allows for the arbitrary collection of information in the form of notes, lists, etc. Additionally, the surface operates as a &#34;host book mark&#34; to allow the location of any page position in the host book. The mechanical binding offers a cluster of surfaces for the purpose of abstracting and classifying information. Additionally, it offers a means for the information to be accessed, and reused in a more flexible manner by providing a &#34;floating&#34; blackboard-like system that can be continually positioned and repositioned to support the state of use of the host book, while staying continually attached to the host book. In this way, a surface intensive area may be deployed, which contains a large reusable space packaged in the effective area of a page of the host book, compactly provided on a repositionable frame. The method enables the reconfiguration of folding surfaces such that they may be placed in arbitrary position with respect to one another or may be removed, substituted, or reconfigured to suit the user&#39;s end application. Thus, the mechanism allows for the continuous collection and depositing of information on its surface as it is swept through the pages of the host blank book. This enables the filtering and selection of information from the host book onto the hypermedia surface, the abstracted information of which may be used in an ad hoc fashion out of the context of the original source materials. 
     Additionally, the ability to position the surfaces within the host book enables a new form of information processing where messages, typically in the form of removable adhesive notes (which may be positioned, removed and repositioned an indefinite number of times) are used in conjunction with the surfaces to allow for the rapid manipulation of classified and typed data. It is preferable for maximum usefulness of such a system that this type of message passing be accomplished within a very short time--e.g., within four seconds. The present invention supports message passing on such a time scale. A complete message passing system can thus be added to a conventional book, allowing the message passing system to operate as a complementary facility without interfering with the original application and use of the host book. 
     In accordance with this invention, a host book configuration could include a host book with a cover, a spine, and pages, and a frame-leaf member bound to the host book in such a way that the host book pages could turn freely and independently of the frame-leaf member, which itself could be manipulated independently of the pages. An alternative host book configuration would include as a host book a simple cover and spine, the pages of the host book comprised solely of frame-leaf members, in which case the book acts in stand-alone fashion as a mechanical hypertext system, with notes and messages passed among the pages of the book thus formed. 
     In accordance with the invention, a mechanical binding system is provided having a fold out leaf. The mechanical binding system has a leaf, a frame, and an adapter with means to combine frames into frame sets, as well as a means for attaching the frame to the host blank book. In the preferred embodiment, the leaf has a plurality of folding surfaces, a mounting surface, and an orientation flap. The orientation flap is connected to the back of the mounting surface leaving a free edge. The frame has an outer arm, a lateral connector arm, and an inner arm. The adapter acts as a coupler for retaining the inner arm of the frame and also functions to connect frames into frame sets as well as for attaching the frame or frame sets, as the case may be, to the host blank book. 
     The mounting surface of the leaf is a plane that is rectangular in shape and whose width is at most equal to the width of the frame. The orientation flap hinges to its back along a line defined by points equidistant from the parallel lateral edges of the mounting surface. The free edge of the orientation flap is pivotally hinged to the outer arm of the frame allowing it to rotate freely about the arm. The connector arm of the frame is of length at most equal to the cover of the book, and greater than the longest page of the blank book, and the inner arm is of length at most equal to the length of the back or binding of the host book, such that the mounting surface and orientation flap can be positioned within or alongside the host book to the right or to the left. The adapter has a means for pivotably and removably retaining the frame and joining one or more additional frames, and has a length substantially equal to the book binding and allowing the inner arm to frictionally fit within the book binding. The adapter has a means for fixing itself to the host book in such a way that it is semi-permanently attached to the book and translationally stationary, allowing the inner arm to rotate 360° around the host book. The leaf member may be positioned within the closed book arbitrarily between any pages, or extended outward to either side of the book and placed on a work surface lying flat such that the pages of the book are in plain view with the mounting surface placed to either side of the book in plain view. 
     Variations on the leaf member would allow for the mounting of a plurality of folding surfaces on the mounting surface. This plurality of folding surfaces could have a variety of folded configurations and could contain various means for retaining loose pages such as envelopes, pouches and the like, and on whose surface might be placed an array of stacks of paper. One type of stack would employ removable adhesive notes on which information could be recorded, where the notes could be removed and posted to other pages of the leaf or of the host book. Another element which could be mounted on the surface might be an electronic device capable of electronic recording of information, such as a computer device. 
     Host book spines come in a variety of types for which the invention is intended to be compatible. One type of host book is a multi-ring binder; another type is a finger clasp binder. A third is a spiral binding. A fourth is a glue-bound type. A fifth is a staple-bound variety with a cover mounted over the staple binding forming a cylindrical gap. A sixth is a glue-bound type with a cover mounted over the binding forming a cylindrical gap. A seventh type of book spine would be formed by a post element which would enable the attachment of frames with inner arms that mate to the post. 
     Other embodiments include various other embedded versions, i.e., versions that fit within a conventional host book of the varieties mentioned. With the appropriate adapters, the embedded versions provide hybrid bindings enabling the combination of the host book spine and its pages in conjunction with a configurable set of hypertext book attachments according to the invention. 
     One set of embedded embodiments utilizes various forms of the inner arm post as a means for attaching directly to a host book spine. In one variation, the inner arm is a post that fits frictionally into the spine. In another variation, the post is formed with a cap which is used as a retaining means. In a third variation the retaining means is a convex hook attached to the end of the post. A fourth variation would use an ear hook mounted along the post. A fifth variation would have the inner arm formed as a hollow tube offering a female socket for joining to the book spine. 
     If desired, a retention tube may be fitted and retained within a spiral (or other type) binding of the host book. This tube would have an inner diameter sized to frictionally and pivotably receive the inner arm of the frame. Alternatively, two frames could be used, with shorter inner arms fitting within the retention tube from the top and the bottom. These could be used to hold one frame both from the top and from the bottom or to hold two separate frames. 
     Another embodiment would include having two frame inner arm members shaped to mate telescopingly, so that one could be inserted from the top of the binding and the other from the bottom. They would telescope together within the binding and so be held in position by friction. 
     Various means could be employed for retaining the leaf on the outer arm of the frame. One variation would provide an adhesive, permanent mount. Another variation would include a set of clamps on the leaf which is snapped onto the outer arm post. Yet another variation would provide means for the post to snap into a tube connected to the leaf&#39;s binding edge. Two frictional variations would include one in which the post fits snugly within a tube attached to the leaf; the other would have the outer arm of the frame kinked slightly such that, upon insertion in a flexible tube attached to the leaf, the friction is increased by direct pressure on the walls of the flexible tube. 
     There are many variations of adapters. One embodiment would be a simple hollow tube which could be attached to a book spine. A second variation would have spurs on the hollow tube. A third variation would have a slim clip for sliding into a cylindrical gap in the host book spine. Another variation would have a broad clip for attaching to a book cover of a paperback glue-bound book. A fifth variation would include a hollow tube with ear hooks along its edge. Yet another variation would include a hollow tube with rivets. A seventh variation would include a hollow tube mounted on a card wherein the card could be a plain stock, a stock with multiple holes punched or a stock element with a folding crease defining the position for mounting the tube. Any variety of hybrid bindings may also be formed by combining the hollow tube adapter with, for instance, a multi-ring binding. Two variations of this type of hybrid would include a version with the tube mounted on the spine of the multi-ring binder, or a version in which the tube/multi-ring assembly is mounted on a card. 
     An adapter for a spiral clasp would mold a retaining tube along the length of the spine so as to let the clasps engage freely while allowing the frame to be attached from above or below. The retaining tube could alternatively be positioned within the inner area of the clasps in such a way as to allow the clasps to engage while allowing the pages to turn freely, as in the case of the spiral. 
     Another adapter would be a card of retangular shape one edge of which houses the retainer for the frame. The retainer might be a tube as in the case above and the card might alternatively have a multi-ring binding on it as well. This hybrid binding would be able to be slipped into the jacket of a host book cover allowing the entire complement of bound leaves and host spine bindings to be moved from cover to cover. 
     In the case of multi-ring bindings, another embodiment would allow an adapter to be fitted into the rings as a page would be inserted. In this case, the adapter would position the retaining means within the inner area of the ring set allowing the frames to be attached without impacting the mechanism for opening or closing the rings. 
     A variation that implements frame sets would have the inner arms of two frames joined in a hollow tube adapter which itself was attached to the host book spine. Another frame set variation would have the inner arms of the two frames join as male-female connectors. A third variation would have the inner arms of each frame attach pivotally to the host book through a direct frictional engagement. 
     Another embodiment would form a new, stand alone type of book with or without conventional pages. In a stand alone embodiment, the frames would be housed in an adapter which became the book spine in and of itself, with the pages of the book including various forms of retained mounting surfaces, each having one or a plurality of folding surfaces mounted thereon.

     DETAILED DESCRIPTION OF THE INVENTION 
     A preferred embodiment of the book attachment of the present invention is the leaf and frame shown in FIGS. 1-7 A mechanical (hypertext) attachment 80, for a &#34;blank book&#34; is provided. As seen in FIGS. 1-7, the attachment has a leaf 50 having a plurality of pages 55-57, a mounting surface 40, an orientation flap 30, a frame 20, and a means for attaching the frame to a blank book 70 at the binding point of the book. An edge 32 of the mounting surface orientation flap 30 is attached to frame 20 via a retaining tube 35, and the frame 20 is attached to the book by means of an inner arm 23 and an adapter 60, where the inner arm 23 fits into the bottom of the adapter 60 through opening 61, with the adapter inserted into the book spine 75 through gap 76. 
     The mounting surface 40, has an orientation flap 30 having a width substantially half the width of mounting surface 40. Orientation flap 30 is attached to mounting surface 40 laterally along the back of mounting surface 40 on a line defined by the points midway in from the parallel edges of mounting surface 40, with its outer edge 32 free to be bound to the outer arm 21 (connected by connector arm 22 to inner arm 23) of frame 20 by a suitable hinge to enable it to rotate about the outer arm 21. 
     Mounting surface 40 hinges on the orientation flap 30 which rotates about outer arm 21 so as to position the flap surface out of the way of the pages of host book 70 allowing for the pages of host book 70 to be turned freely and enabling mounting surface 40 to be reinserted arbitrarily at any point in host book 70 like a book mark, and allowing book 70 to close flatly with the connector arm of frame 20 seated within the perimeter of the covers of host book 70 and not interfering with any of the pages of the host book. The plurality of pages 55-57, attached to mounting surface 40, thus become an add-on to the host blank book 70, and include one or more folded surfaces, envelopes, pouches, or the like capable of holding or storing information, notes, lists, removable adhesive notes, or loose pages of any type, each plane offering a plain view of its contents when opened to. And as shown in FIGS. 2 and 3, with inner arm 23 of frame 20 attached to the host blank book 70 by means of a suitable adapter 60 that allows the combination of frame 20, orientation flap 33, and mounting surface 40 to rotate about the binding point of host book 70 to which it is attached. The leaf can be rotated about outer arm 21 of the frame 20, and the entire frame and leaf can be rotated about spline 75. The leaf mounting surface 40 is so attached to frame 20, and the frame 20 so attached to book 70, that mounting surface 40 and its plurality of surfaces 50, may be positioned on either side of blank book 70, to be extended to either side of book 70 or, as shown in FIG. 1, to be folded into the book on either side while retaining the same orientation of the mounting surface 40. In this way the plurality of pages 55-57 may be placed in a position allowing their outer edges 59 to be accessible in the same fashion of the pages 73 of book 70. If mounting surface 40 is flipped on orientation flap 30 so that the edges 59 of the floating pages 55-57 are adjoining book spline 75, the retaining edge 35 of orientation flap 30, the edge 44 of the mounting surface 40 and the flat binding edge 54 of the plurality of pages form a single edge. The single edge formed by these surfaces is accessible as a single page operating as a marker. Orientation flap 30 and mounting surface 40 may be semipermanently joined at that single edge using hook-and-loop-type fasteners, magnets, tape and the like, or by a spring or clip mechanism. The purpose of providing a joining means is to allow mounting surface 40 and orientation flap 30 to join and operate cohesively as a single surface when desired, while not restraining their separation and free motion, and allowing for the reconfiguration of the mounting surface to a position on either side of the book, either within or along side the host book. 
     FIG. 4a shows an electronic module, 40a, here in shown as a calculator mounted on surface 40. FIG. 5a shows the cross section view of the electronic module. It is possible to construct such an assembly by attaching the orientation flap directly to the electronic module. Alternatively, the orientation flap may be constructed in a variety of ways, not limited to a flap, a wire frame or the like structure. The electronic module may be mounted in a pocket or otherwise fixed to the orientation flap. The electronic device may be any device not limited to a calculator, application specific microprocessor and the like. 
     The sizes of the respective surfaces have been described for a preferred use within a host book. However, the above described mechanism would work well with surfaces having lengths of varying proportion, while still being within the scope of the invention. The book attachment shown herein provides a repositionable surface which allows for a surface intensive blackboard with optional surfaces which can be labelled, typed, categorized and retyped as suits the application, as well as to be placed as a mark in any page of a book. 
     Alternate embodiments employ variations on the frame, types of leaf, means for binding the leaf to the frame, and means for binding the frame to the host book, each variety of host book binding style requiring a different preferred mechanism of attachment. 
     As shown in FIG. 34, a frame may utilize two members where the connector arms 22 are identical in length, and outer arms 21 join in supporting a leaf member. This configuration would be employed for increased stability of the assembly. FIG. 34a shows a means for adjusting connector arm 22 by means of a slide adjustment 24. 
     FIG. 40 shows a frame set which would be employed for supporting two leaves. In this case the connector arms 22 are sized to allow the frame outer arms 21 to pass one another without interference. In FIGS. 13 and 40, the frame inner arms mate male-to-female, while in FIG. 41 they are joined by a hollow tube adapter 60. Another variation of this would have the inner arms 23 of FIG. 41 join directly to the host book spine without the aid of adapter tube 60. FIG. 8 shows how the frame set of FIG. 41 would be utilized in a spiral binding. 
     Various leaf types would offer different options in the use of a deployed hypermedia system. FIG. 42 shows a basic configuration where the leaf 46 is a simple rectangle which could be deployed as a mounting surface FIG. 43 shows a dual leaf configuration with leaf members 47, 48 joined at their binding edge. FIG. 44 shows the leaves 48, 49 joined to form a folding rectangular shape with one binding edge 42. 
     FIG. 45 shows the preferred embodiment of the mounting surface 40 with orientation flap 30 which operates as an orientation enabler that preserves the orientation of surface 40 in each configuration about the frame. 
     Various surfaces could be attached to mounting surface 40. FIGS. 46-49 show a different configurations of surfaces used to support arrays of note stacks 91. As shown here, note stacks 91 themselves are sets of removable adhesive notes which provide a means for collecting information and can be written on incrementally and pasted many times among the pages of the attachment as well as among the pages of the host book. The plurality of folds could also be labeled for various purposes. The folds could host pre-printed forms, envelopes, pouches, or electronic devices such as calculators and other application-specific microcomputers. For example, FIGS. 4a and 5a show a calculator module 40a mounted on mounting surface 40. 
     Various means can be employed for retaining the leaf on the outer arm of the frame In FIG. 39, the leaf 30 is attached to the outer arm 21 with a permanent, flexible, adhesive mount 30a. Another variation shown in FIG. 38 would employ a set of clamps 39 on the leaf 30, which snap onto the outer arm 21. Yet another variation, FIG. 37, shows a means for the posts 21 to snap into a tube 35 to the leaf&#39;s binding edge. The means for snapping could vary. One type includes the use of a post 21 with a bulbous end 21a that slides past a flexible construction 35a. Two frictional variations are shown in FIGS. 35 and 36. In FIG. 35, post 21 is a straight member that fits frictionally into tube 35. In FIG. 36, the post is kinked slightly to place varying pressure on tube 35 ensuring a frictional fit. 
     Leaf members may be attached to either outer arm 21 or connector arm 22. FIG. 55 shows a host book with a frame supporting two leaf members 40. 
     Host book spines come in various types. FIG. 14 shows a spine formed by a post 63 capable of supporting two female inner arms, one of which is shown at 23. FIG. 29 shows the gap 76 formed along spline 75 when a cover is adhered to a set of either glue- or staple-bound pages. FIG. 30 shows a side view of the gap when the book is open and FIG. 31 shows a side view of the gap when the book is closed. FIG. 32 shows a similar gap formed by a different variation of glue-bound binding. FIG. 33 shows a side view. FIG. 27 is a side view of finger clasp binding shown in FIG. 28. A hollow tube adapter 60 is shown as part of the binding as a means for hosting frame inner arms. The adapter tube is sized to allow the pages to turn freely. The spiral binding gap of FIG. 8 is another type of host spline for which the present invention is compatible. Additionally, a variety of hybrid bindings formed by an adapter and a standard multi-ring binding are shown in FIGS. 25, 26. In FIG. 25, a hollow tube adapter 60 is fitted directly to spine 75 of the multi-ring binding. In FIG. 26, the multi-ring binding 75 and the adapter tube 60 are mounted on a card 66. The card may be deployed in the jacket of a host book cover. 
     The inner arms of the frame can provide a means for retaining itself in some standard book spines. FIGS. 9-12a show various inner arm modifications. FIGS. 9 and 9a show a simple post, preferably with a rounded or tapered tip, which would mount frictionally in the cylindrical gap spine of, for example, FIG. 29. FIGS. 10-12a show variations that adapt for spiral or tube fittings as a means for retaining the tube more securely while enabling pivotal action. FIGS. 10 and 10a show post 23 with a cap 25. This could be a removable element or a rivet. FIGS. 11 and 11a shows post 23 with a hook which would fit over the top loop of a spiral, for example. FIGS. 12 and 12a shows an ear hook which would be inserted into the gaps between spirals as a means for retaining the post inner arm 23 within a spiral binding. 
     Means for retaining a hollow tube adapter are shown in FIGS. 15-24a. FIGS. 15 and 15a show the basic hollow tube adapter 60. It can be deployed in most any modification, as shown in FIG. 8. A modification shown in FIGS. 16 and 16a which would permit a frictional fit in a cylindrical gap would have spurs 63 along the tube. This figure shows spurs that permit the tube to be slid freely in one direction, but provide abrasion when the tube is slid in the opposite direction. FIGS. 17 and 17a shows tube 60 fitted inside clip 64 for mounting in a gap, a spiral, or the like. FIGS. 18 and 18a show tube 60 with ear hooks 24 formed along tube 60 as a means for attaching the tube to a spiral. FIGS. 19 and 19a shows tube 60 with a rivet attachment 65 for fixing tube 60 to a book spine. 
     FIGS. 20 and 20a shows tube 60 on a card adapter 66 for sliding into a host book cover. FIGS. 21 and 21a show a card 67 with multiple holes punched. This adapter would permit the tube to be placed in the inner area of a multi-ring binding. FIGS. 22 and 22a show tube 60 with a clamp-style attachment 68. This would allow the tube to be slid onto the back cover of a paperback book or other style of book cover of a firm rectangular shape. FIGS. 23 and 23a shows the hollow tube adapter 60 mounted in the center of card 69. This fitting would permit the adapter to fit into a cylindrical gap of the type shown in FIG. 32. FIGS. 24 and 24a show tube 60 mounted in a folding card 69a. This type of fitting would allow the tube to be deployed in a book cover as a standard feature of the cover. The tube could be on the inside, outside, or formed directly as part of, the folding card. 
     A host book can have primary and secondary spines. FIG. 56 shows a secondary spine 78 positioned equidistantly between the primary spine 75 and the outer edge of the right cover. Additionally, a secondary spine 78 is shown mounted on the edge of the left cover of the host book. A frame 20 is mounted in each secondary spine 78. 
     For the preferred embodiment, there are additional variations shown in FIGS. 50-54. FIG. 50 shows a mounting surface and orientation flap perspective view. The elements 110, 111 could be made of thin metal strips. Element 112 could be a magnetic element. This would permit the joining of corners a and c or alternatively e and c on a semi-permanent basis. FIG. 51 shows one means for forming the mounting surface and orientation flap from one piece of material. The corners b and d are joined in a surface 121, 122 being adhesively connected. Retaining element 112 could be concealed between the surfaces. FIG. 52 shows the leaf of FIG. 51 laid out in a single plane. Hollow tube adapter 35 could also be another type of binding. FIG. 53 shows the addition of surfaces 124, 125 which, along with an arbitrary number of additional surface extensions, could be folded to form a plurality of surfaces on top of the mounting surface, as shown in FIG. 54 where the entire leaf is comprised of one piece of material. 
     The frame can be made of any stiff, inflexible material, with a colored or coated finish to match the host book requirements. The surface, when made of polyester material such as MYLAR® or of a woven plastic such as TYVEC®, can be given a plastic coating on its surface using a material like CLEAR SEAL®, or may be a stiffened plastic whose surface offers sufficient adhesion to allow removable adhesive notes to be easily posted and reposted without peeling off. The color of the surfaces can also be selected to match the host or may be color coded to support the application. The surfaces may also be die-cut to enable selective access. They may also contain translucent or opaque pouches for other information handling, or may be shaped to hold an electronic device such as a microcomputer or the like. 
     The mechanical (hypertext) attachment forms a (hyper) binding system functioning as a list machine which marks any page it is folded into when the book is closed, rests within the perimeter of the cover on either side of the book when the book is open, and allows the pages of the host blank book to sweep past it in either direction when the book is opened and the host blank book pages are turned. One skilled in the art will appreciate that the present invention can be practiced by other than the embodiments described, which are presented for the purpose of illustration and not of limitation, and the present invention is limited only by the claims which follow.
