Congress established the Federal Depository Library Program (FDLP) to provide free public access to federal government information. The program's origins date to 1813, when Congress authorized the printing and distribution of additional copies of the Journals of the House and Senate, and other documents the chambers ordered printed. Quantities were to be "sufficient to furnish one copy to each executive, one copy to each branch of every state and territorial legislature, one copy to each university and college in each state, and one copy to the Historical Society incorporated, or which shall be incorporated, in each state." At various times, the program was expanded to include federal executive branch publications. The current structure of the FDLP program was established in 1962. Access to government information is provided through a network of depository libraries across the United States. In the past half-century, information creation, distribution, retention, and preservation has expanded from a tangible, paper-based process to include digital processes managed largely through computerized information technologies. Today, government (and most other) information is typically "born digital," or originated as a digital product such as a word processing document or spreadsheet. The material may then be produced in tangible, printed form, but is with greater frequency distributed by electronic means via website or other electronic dissemination technology, and retained for archival purposes in searchable electronic databases. In many cases, born digital material that previously appeared only in paper form is available only in digital form. In other cases, digital information, including websites, blogs, datasets, and audio or video content, is not intended for tangible distribution. Some materials are available in both tangible and digital forms. The transition to digital information raises a number of issues that may be of interest to Congress. Some of the possible concerns focus on access to government information in an environment in which tangible and digital materials are available, and issues related to the security and authentication of digital materials. Other areas of possible concern include the management and digitization of tangible materials, permanent retention and preservation of digital content, and costs associated with these activities. While issues related to the emergence of digital information have implications for a number of government programs and policies, this report discusses those implications as they affect FDLP. These concerns may be addressed in their own right, or in the context of user demand for FDLP information, for which there is no uniform metric over time, or comparatively among current FDLP institutions. Acronyms or abbreviations used in this report are summarized in Table 1 . A glossary in the Appendix provides definitions for the specialized information management terms used in this report. FDLP is administered under the provisions of Chapter 19 of Title 44 of the United States Code by the Government Printing Office (GPO), under the direction of the Assistant Public Printer, Superintendent of Documents (SuDocs). Under the law, FDLP libraries receive from SuDocs tangible copies of new and revised government publications authorized for distribution to depository libraries, and are required to retain them in either printed or micro facsimile form. Depository libraries--which include state, public and private academic, municipal, and federal libraries--are required to make tangible FDLP content available for use by the general public, which GPO defines as including all people in a depository library's relevant region and congressional district. In support of that effort, depository libraries provide resources to manage collection development, cataloging, bibliographic control, adequate physical facilities, collection security and maintenance, and staffing. Neither statute nor current GPO guidance specifies how depository libraries must deploy those resources in support of FDLP. Ownership of publications provided by SuDocs to depository libraries remains with the United States government. Observers note that distributing publications to depository libraries has the effects of long-term preservation of federal government information in widely dispersed settings, and free, local access to that information. The costs of providing preservation and access are also widely distributed. Under 44 U.S.C. 1912, not more than two depository libraries may be designated as regional depository libraries (hereinafter, regional libraries) in each state and Puerto Rico. Regional libraries are required to retain tangible government publications permanently, with the exceptions of superseded publications, or unbound publications that are issued later in bound form, which may be discarded as authorized by SuDocs. There are 47 regional libraries in the FDLP. Among their duties is to provide materials to patrons directly, or through interlibrary arrangements with selective libraries within their areas of responsibility. Further discussion related to regional libraries is provided in " Regional Library Activities ," below. Selective depository libraries (hereinafter, selective), are partially defined in Title 44, and include all FDLP participants that are not regional libraries. Whereas regionals receive all FDLP tangible content provided by GPO, selectives may choose among classes of documents made available. Selective libraries that are served by a regional library may dispose of tangible government documents after retention for five years, subject to certain conditions. Those selective libraries that are not served by a regional library are required to retain government publications permanently, subject to the same limitations placed on regional libraries. There are approximately 1,150 selective libraries in the FDLP. Authorities governing FDLP are based on a paper-based information creation and distribution environment. Some tangible government publications are still distributed to depository libraries; during FY2011, GPO distributed approximately 2 million copies of 10,200 individual tangible items to depository libraries. Some tangibles may have no publicly available digital counterpart if the owner of the information does not authorize GPO to make it available. SuDocs maintains a list of titles that "contain critical information about the U.S. Government or are important reference publications for libraries and the public." As a consequence, the agency has determined that "their availability ... in paper format has been deemed essential for the purposes of the FDLP." Nevertheless, much of the content that SuDocs has provided previously in tangible formats is now available in digital formats through GPO's FDLP Electronic Collection, which provides access to government information to Internet users without cost. The Collection consists of four elements: Core legislative and regulatory products that reside permanently on GPO servers and are made available through GPO's Federal Digital System (FDSys); Other remotely accessible products managed by GPO or other institutions with which GPO has established formal agreements. Access to some of the products in this category is provided by GPO through resources outside the scope of FDSys. Access to the products of official GPO content partners is provided by those entities. GPO provides access to those materials through the Catalog of U.S. Government Publications (CGP); Remotely accessible electronic government information products that remain under the control of the originating agencies that GPO identifies, describes, and to which it provides links; and Tangible electronic government information products distributed to federal depository libraries. The emergence of a predominantly digital FDLP may call into question the capacity of GPO to manage the program given its existing statutory authorities. Whereas GPO is the central point of distribution for tangible, printed FDLP materials--an activity that it continues--its responsibilities are more diverse, and may be less explicitly specified, regarding its distribution of digital information. In some instances, GPO carries out activities to distribute digital information that are similar to its actions regarding print materials. In others, GPO provides access to digital content that it does not produce or control. SuDocs has archiving and permanent retention authorities for tangible materials, which are exercised by the distribution of materials to depository libraries. At the same time, those authorities do not envision digital creation and distribution of government publications. GPO appears to have some authority to manage digital FDLP materials and other aspects of the program, subject to congressional approval. At the same time, explicit digital distribution authorities that provide for online access to publications, including core legislative and regulatory products, do not directly address GPO's retention and preservation responsibilities for digital information. A number of efforts related to the program have been initiated by GPO and groups representing a number of libraries that participate in FDLP. These have included certain regional library activities; studies of the program by a private organization; proposals by a consortium of FDLP libraries to advance the consolidation, digitization, and cataloging of tangible collections; and a study of FDLP coordinated by GPO. Although each state may have up to two regional libraries, the FDLP currently has 47 regional libraries. Six states have two regional libraries; seven regionals serve more than one state, territory, or the District of Columbia; and three states have no designated regional library. Arrangements allowing multi-state regional libraries do not appear to be sanctioned in 44 U.S.C. Chapter 19, but according to GPO, some multi-state agreements date to the years following the passage of the 1962 FDLP program revisions. In recent years, proposals have been offered by private research groups, individual FDLP libraries, and consortia of FDLP institutions for certain regional libraries to share or assume responsibilities for selective libraries in other states. One proposal, submitted to GPO in 2007, would have created a "shared" regional between the depository libraries of the University of Kansas and the University of Nebraska. Another proposal, submitted in 2011, would have authorized the Minnesota regional to assume responsibility for selective libraries in Michigan. GPO submitted the Kansas-Nebraska regional plan to the Joint Committee on Printing (JCP), which oversees the agency. On February 27, 2008, Representative Robert A. Brady, JCP chair, denied committee approval of the plan, based on an analysis "that neither the language nor legislative history of 44 U.S.C. 1914 supports" authorizing the creation of a shared regional library. In the summer of 2011, the Library of Michigan, which then served as the regional for that state, proposed that the University of Minnesota assume responsibility to provide regional services for Michigan selectives. In a September 15, 2011, response to the Library of Michigan, GPO noted that existing FDLP authorities do not explicitly authorize multi-state regionals and that "such arrangement should be approved by the Joint Committee on Printing under the provision of 44 U.S.C. 1914." GPO stated that it would not be submitting the proposal that the University of Minnesota serve as the regional depository for Michigan selectives to JCP due to concerns about the capacity of the University of Minnesota to serve Michigan selectives, collection management procedures, and what the agency described as "the lack of equal and equitable access for government publications for the people of Michigan." In September 2010, GPO contracted with Ithaka S+R (Ithaka), a private consulting and research entity, "to develop practical and sustainable models for the FDLP that retain and support the long-standing vision, mission, and values of the Program in an environment increasingly dominated by digital technology." The resulting report, Modeling a Sustainable Future for the United States Federal Depository Library Program's Network of Libraries in the 21 st Century: Final Report of Ithaka S+R to the Government Printing Office (Ithaka Report), was delivered to GPO in May 2011. Ithaka reported that their research drew conclusions in three categories, including collections and formats, services, and the network of depository libraries. The report stated that users of government information increasingly prefer to access government documents and other collections in electronic form. At the same time, the report found that tangible collections support some types of access demand. Consequently, tangible and digital collections are expected to exist together for the foreseeable future. The report noted that since more content is available online, libraries are no longer exclusive points of access to collections, but remain a source of unique services such as search and reference assistance. The report asserted that current levels of support within the FDLP "are inadequate to effectively meet the needs of the American public," and suggested that some program growth may be possible by improving opportunities for libraries principally interested in providing government information services. The report did not specify which opportunities might be available to depository libraries. The report noted that there may be new opportunities within FDLP related to the management and preservation of digital collections, and that some opportunities might be addressed by having existing networks of libraries work in collaboration on various projects. One particular challenge cited by Ithaka is the distribution of regional libraries by state boundaries (instead of other factors like population density or collections usage), which the report argues creates strain on some regional libraries to provide services to selectives in their states or regions. Ithaka incorporated its findings into a number of research, analytic, and modeling activities, and proposed a broad direction in which GPO and depository libraries might proceed to provide access to government information. Without making specific recommendations, Ithaka focused on three broad areas in which the report asserted there was general agreement among depository libraries to support the following activities: respond to the demands of providing access to tangible materials; provide access to and preservation of digital materials; and provide government information services. In support of those efforts, Ithaka identified several themes it deemed important to sustaining FDLP, including allowing depository libraries to define their activities to match their local missions and circumstances; and embracing collaboration and coordination among depository libraries beyond the current state-centered regional and selective model. Ithaka asserted that some of the various themes it suggested might require statutory changes, new operating practices by GPO, or consideration of a better match between depository libraries' interests and capacities to participate in FDLP. In August 2011, GPO rejected the Ithaka Report, stating that "[a]fter a very comprehensive analysis by GPO, the final report prepared by Ithaka was deemed unacceptable under the terms of the contract. The models proposed by Ithaka are not practical and sustainable to meet the mission, goals, and principles of the FDLP. Nonetheless, GPO believes that the final report has some value as we move forward with the library community to develop new models and increase flexibility in the FDLP to ensure the vibrant future of the Program in the digital age." GPO did not provide a detailed, publicly available explication of its decision. At the same time, some Ithaka recommendations appear to be beyond the scope of GPO's current statutory authority to oversee FDLP, and the responsibilities of FDLP participants. On April 27, 2011, the Association of Southeastern Research Libraries (ASERL) approved an implementation plan for the management and disposition of federal depository library collections in its member libraries. The implementation plan was a step in ASERL's efforts to develop what it called a "Collaborative Federal Depository Program." In its implementation plan, the group asserted "that the best means of providing broad public access to these collections is through online access to digital and digitized copies. Management of the tangible collections should include efforts to support or participate in initiatives to create a comprehensive, authentic digital collection in the public domain." ASERL argued that its plan would complement efforts to manage the tangible collections held by depository libraries in its member institutions. The ASERL plan would make efforts to define what constitutes a comprehensive FDLP tangible collection; establish two such comprehensive collections; and establish "centers of excellence," FDLP regional libraries that would focus on cataloging, inventorying, and acquiring publications in an effort to establish a comprehensive collection of agency-specific materials. Part of the ASERL effort included the development of a documents disposition database. Under the ASERL plan, materials that depository libraries intend to withdraw from their collections would be made available for a period of 45 days prior to being withdrawn. During that period, the materials could be requested first by centers of excellence, and second by FDLP regional libraries, followed by FDLP selectives in the southeast region. At the end of the 45-day selection period, the ASERL plan called for the discarding of materials, "items not requested by another library within the southeast region, unless the items are rare or likely to be of significant interest beyond the region and therefore should be included in the national 'Needs and Offers List' maintained by the Superintendent of Documents." On November 4, 2011, SuDocs responded to ASERL, writing that the proposed disposition tool was "not in compliance with the legal Requirements & Program Regulations of the Federal Depository Library Program (FDLP)." SuDocs recommended that ASERL's disposition tool be revised to allow FDLP regionals to acquire materials from among collections of selective libraries within the state the regional serves, followed by other selectives in the state, followed by FDLP libraries outside the state. On February 12, 2012, ASERL proposed to amend its implementation plan to give priority to regional and selective libraries within states, followed by depository libraries within the southeast region. On February 13, 2012, SuDocs approved the proposed revisions and requested the opportunity to review a revised implementation plan. Further response from ASERL and a final decision by SuDocs are pending at the time of this writing. Since an October 20, 2011, public forum for the FDLP community, GPO has been developing a study of the FDLP program "to effectively assess the current needs and future direction of the FDLP for both individual libraries and states." The study will be based in part on data collected through a questionnaire sent to individual depositories to identify issues. Data generated by individual depository libraries will be incorporated into state-focused action plans incorporating the feedback of depository libraries within a state. GPO states that "[c]onsensus of opinion about the key issues facing depository libraries today and in the future is the key to moving forward with change," and notes that the current study is a component of "a larger FDLP study that will also examine primary and secondary data, laws governing the program, and possible program models." in an effort to develop a plan "for the future of the Program ... based on a shared vision with member libraries." GPO has not publicly announced when the results of the depository survey or the state action plans will be available, or when those results will be integrated into the larger study of FDLP. A number of issues regarding FDLP and policy related to the transition to digital government information that might be of interest to Congress arise as a consequence of digital creation, distribution, and preservation of government information. These issues are in some cases interrelated, and may have been addressed in part in the Ithaka Report and ASERL proposals, or may receive further consideration in GPO's studies. Some of the issues may affect FDLP, and extend beyond the program to a variety of contexts related to the management of government information in tangible and digital forms, and include Maintenance and availability of the FDLP tangible collection; Retention and preservation of born digital information; Access to FDLP resources; Authenticity and accuracy of digital material; Robustness of the FDLP Electronic Collection; and Cost of the FDLP and other government information distribution initiatives. The FDLP collection, which incorporates materials dating to 1813, is estimated to contain approximately 2.3 million items. As much as one-third of the tangible collection, including most items created prior to 1976, is not catalogued. Most depository libraries do not have a full complement of depository materials because they joined the program at various times after 1813, and are not required to acquire materials retrospectively, or retroactively in the event of collection loss. Estimates of the usage of tangible FDLP materials are not readily available. This is due in part to the highly decentralized manner in which materials are stored and accessed, differences in the ways depository libraries might track collection use, and the lack of requirements to develop and maintain utilization metrics. There are some suggestions that parts of the collection might be underutilized, due to the lack of cataloging information for much of the collection distributed prior to 1976, when GPO began creating cataloging information. Others suggest that some materials that are cataloged and available receive little use. On the other hand, it has been suggested that some tangible items that had not been used were more frequently accessed when made available online. In the absence of any systematic inquiry, it cannot be determined whether the lack of utilization is the result of minimal demand, lack of catalogue information for some materials in the FDLP collection, or inadequate communication of the collection's availability. As seen in the ASERL proposals, some depository libraries see opportunities to digitize tangible FDLP collections to ensure their preservation and to make them more available to users who are better able to access the materials online than to visit libraries. Such efforts might provide broader access to the public, assuming that technological infrastructure is in place to ensure sufficient access to the Internet. Provision of digital government information in digital form could reduce the costs of maintaining a tangible collection, or provide the opportunity to reduce the number of copies of tangible government publications held by depository libraries through consolidation of collections. On the other hand, as discussed in more detail below, there is no consensus on what constitutes a sufficient number of paper copies. Further, it is possible that the costs of ongoing maintenance and technology upgrades necessary to support digitized materials could be higher than the current costs to maintain tangible collections. See " Retention and Preservation of Born Digital Information " and " Costs of FDLP and Other Government Information Distribution Programs ," below. Any effort to digitize or reduce the number of tangible copies appears to be beyond the scope of authorities granted to SuDocs or depository libraries under current law. Nevertheless, the question of how to retain and preserve government information contained in tangible form alone, and to provide access to that information to all who wish to see it, raises a number of questions. At the outset, these questions may lead in two directions: one related to the retention and preservation of tangible materials in their original form, the second focused on efforts to transition tangibles to digital formats. Questions related to the retention and preservation of tangible materials in tangible formats arise with regard to the following: preservation of decaying tangibles; establishing how many complete, tangible copies may be necessary to ensure permanent retention of records of government activities; and access for the general public when digital materials do not meet user needs. With regard to preservation, it would be necessary to have a more fully cataloged FDLP collection to be able to determine what the preservation requirements are. On questions about the number of tangible copies to be retained permanently, there is little consensus. Some studies note the opportunities to consolidate collections to free up storage space, and potentially reduce costs, while still ensuring that library users' needs are met. Others cite a lack of data to demonstrate how many copies might be needed to meet those needs. The ASERL plan calls for the development of two complete sets for the use of libraries within the southeast region. Another proposal calls for the creation by GPO of two national retrospective collections, to be housed separately in secure facilities. One study, focusing not on government documents, but on the number of copies of scholarly journals in academic settings that must be retained in print form to ensure enduring access, ranges from as few as 6 to as many as 96 copies, depending on the manner of storage and the time period during which the materials are expected to be available. A number of questions related to the retention and preservation of digitized materials are similar to issues that arise in the consideration of born digital materials, and are discussed in more detail in " Retention and Preservation of Born Digital Information ," below. Questions specifically related to digitized tangibles arise in the following areas: The costs of digitizing tangible collections; The authenticity and ownership of digitized versions of tangible publications; The disposition of original publications that are digitized; The extent to which the costs of these efforts represent a resource savings or increase in comparison to current FDLP practices or a redistribution among FDLP participants; and Whether these efforts change the extent and nature of public access to government information. In addition to the technical and procedural aspects, any discussion of tangible materials would likely involve consideration of the costs of activities necessary to preserve them in their original manifestations, or to ensure their access through cataloging or digitization. Estimates of the cost of such efforts across the FDLP program do not appear to have been developed. Digitization has a relatively short history. As a consequence, less is known about the long-term, archival retention of digitized or born digital materials than about the retention of information in paper or other tangible forms. Differences between the production and distribution processes for tangible items and digital materials affect distribution in the short term, and may have implications for accessibility over longer terms. For example, whereas tangible items are produced and distributed through FDLP, born digital materials may be accessible through the FDLP Electronic Collection, or available only through federal executive branch agency websites, or the websites of GPO content partners. This may have implications for the systematic collection and cataloging of materials, or, as just mentioned, public access to them. Born digital materials--such as databases, websites, and publications--may also be dynamic, and their content more readily changed than tangible materials. This may raise questions about version control, or strategies for identifying and capturing different versions of materials in their entirety for evaluation for archival retention. Other areas of concern are the formats in which born digital materials are produced, the media on which they are stored, and the implications of changes in either for the accuracy or authenticity of the information preserved. The potential consequences of format obsolescence, media failure resulting in data loss, and the challenges of migrating government information to newer formats or storage solutions appear to be incompletely addressed by those who create information technology systems, government agencies that create and distribute information, information professionals who curate and preserve those materials, and users who may rely on contemporary and historical government information in digital formats. Consideration of the questions and challenges surrounding the permanent retention of digital information has occurred in the past four decades, but has yet to identify solutions that are widely accepted. The emergence of digital delivery of government information outside the FDLP program may offer increased access to government information to those who might not be able to visit depository libraries. An underlying assumption of the Ithaka Report, for example, is that FDSys is functional and available, and that most users have access. While this model appears to go beyond the current statutory framework for FDLP, the apparent reliance on the FDLP Electronic Collection raises a number of questions for FDLP participants and users of government information. Unlike tangible collections, digital government information is not physically provided to depository libraries, but is provided through the Internet by GPO and its content partners to depository libraries and directly to users with Internet access. The information itself is contained on a server and in any backup facility that may be utilized. For depository libraries, this may raise concerns related to their collection development practices. If digital access is assured, it may be possible to reduce tangible collections. On the other hand, if digital access is not robust, it may be necessary for depository libraries to support access to digital materials while maintaining tangible collections. Potential users may or may not benefit from digital delivery arrangements if their Internet access is not sufficient to access resource intensive, authenticated materials served through FDSys. Another set of concerns may focus on the availability of information that is not physically present in depository libraries. Other concerns may arise if available search resources do not yield the information a user seeks. In addition to the user and depository concerns, the emergence of the FDLP Electronic Collection as a digital repository raises question about the security and availability of government information. One of the purported benefits of the tangible-based FDLP program is that widely distributed publications would provide a safeguard against the unavailability of that information if some copies were lost or destroyed. The use of the FDLP Electronic Collection may raise the following concerns in the context of digital information: Where do FDLP Electronic Collection data reside? Are current data management protocols sufficient to ensure no loss of data availability, and assured access? Are those protocols similar in GPO, other federal agencies, and non governmental partners that provide content? What backup, and information distribution and assurance policies, are in place? Depository libraries appear largely to have borne the costs of the FDLP program since its establishment. There is no mechanism in 44 U.S.C., Chapter 19, to fund depository costs of managing materials, staff, and physical plant needs, and providing public access. In an era characterized by dwindling resources, particularly in state and local governments and public libraries, the costs of maintaining FDLP tangible collections, which, according to GPO, remain the property of the United States government, have become prohibitive to some depository libraries. The emergence of digital delivery has had cost implications for information providers. Whereas the costs of tangible support rest largely with depository libraries, the costs of providing digital materials, including storage of digital materials, Web development, maintenance, and upgrades, fall on GPO for FDSys and other entities that provide content through the FDLP Electronic Collection. Over time, the costs of digital delivery could require additional appropriations for GPO and other federal content providers, or force those agencies to revaluate service levels in a hybrid system of tangible and digital delivery. Whereas the costs of a tangible FDLP fall largely on depository libraries, GPO, in its FY2013 budget submission, notes that in "a primarily electronic FDLP, the costs of the program are increasingly related to identifying, acquiring, cataloging, linking to, authenticating, modernizing, and providing permanent public access to electronic Government information, which involves recurring costs" to GPO. These costs may continue to increase as more digital information is created, and older data, software, and hardware must be upgraded to ensure ongoing digital availability. There is no publicly available estimate of what those costs might be over time. The emergence of digital information has had notable effects on the types of information created, including databases, video, audio and Web-only materials, and the manner in which that information is distributed beyond tangible, paper copies. A clear consequence of those changes is the emergence of general agreement that the statutes governing FDLP, and last visited by Congress before the digital era of information creation, collection, and distribution, are insufficient to regulate contemporary processes carried out by government and depository institutions. A related question is whether existing authorities can support GPO and depository libraries as they address the demands of users of government information and the general public. A particularly complex question is what solutions might create a more robust FDLP that is better equipped to meet the demands of providing government information to American citizens. It appears that a number of social, political, and technical concerns must be addressed more systematically before a policy regarding the future of FDLP can be developed. In moving toward the development of a more contemporary FDLP, Congress might consider the following issues: Development of methods, materials, and technologies to ensure the long-term preservation of digitized and born digital information; A more inclusive definition of materials to be included in FDLP collections. Under current law, "government publications" are defined as "informational matter which is published as an individual document at Government expense." While seemingly broad with regard to tangible materials, the law does not take into account government publishing programs outside GPO authority. The somewhat vague language could also lead to differences by agency in the type of materials that get into FDLP collections. In addition, there is no clear link to which digital material should be included in FDLP collections; The extent to which there is a need to expand the current institutional model of FDLP beyond regional and selective libraries. Information management is a more specialized activity now than when the current version of FDLP was established. Activities that might be of benefit to the program could include curatorial services, tangible preservation or digitization, information integrity assurance (e.g., digital signatures or other authentication schemes), and the cataloging of older tangible materials. These activities could occur within current FDLP institutions or by other libraries or other entities that could provide assistance without managing collections; and The costs of the program to the federal government and depository institutions, and how long-standing funding models might affect the program in the digital era.

Summary:
Congress established the Federal Depository Library Program (FDLP) to provide free public access to federal government information. The program's origins date to 1813; the current structure of the program was established in 1962 and is overseen by the Government Printing Office (GPO). Access to government information is provided through a network of depository libraries across the United States. In the past half-century, information creation, distribution, retention, and preservation has expanded from a tangible, paper-based process to include digital processes managed largely through computerized information technologies. The transition to digital information raises a number of issues of possible interest to Congress. This report discusses those possible concerns as they affect FDLP. These issues, which are in some cases interrelated, may not only affect FDLP, but also extend beyond the program to a variety of contexts related to the management of government information in tangible and digital forms. Issues include the following: maintenance and availability of the FDLP tangible collection; retention and preservation of digital information; access to FDLP resources; authenticity and accuracy of digital material; robustness of the FDLP Electronic Collection; and the costs of FDLP and other government information distribution initiatives. The emergence of a predominantly digital FDLP may call the capacity of the statutory authorities GPO exercises into question. Whereas GPO is the central point of distribution for tangible, printed FDLP materials, its responsibilities are more diverse, and may be less explicitly specified, regarding its distribution of digital information. In some instances, GPO carries out activities to distribute digital information that are similar to its actions regarding printed materials. In other instances, GPO provides access to digital content that it does not produce or control. The agency has archiving and permanent retention authorities for tangible materials, but those authorities do not envision digital creation and distribution of government publications. Digital distribution authorities provide for online access to publications, but are silent on GPO's retention and preservation responsibilities for digital information. These concerns may be addressed in their own right, or in the context of user demand for FDLP information, for which there is no uniform metric. A number of efforts related to FDLP have been initiated by GPO and groups representing a number of libraries that participate in FDLP. These have included certain regional library activities; studies of the program by a private organization; proposals by a consortium of FDLP libraries to advance the consolidation, digitization, and cataloging of tangible collections; and a study of FDLP coordinated by GPO.
