Future Directions for Metadata Remediation for Metadata Aggregators
Greta de Groat
Commissioned by DLF Aquifer and supported by a grant from The Gladys Krieble Delmas Foundation, this report was written for metadata specialists, programmers, project planners, and systems architects, and librarians to help them make decisions about how to allocate resources for metadata creation, enhancement, and remediation by examining the feasibility of developing tools into production services for automating the cleanup and enhancement of metadata records. It is a thoughtful review of commercially and freely available state-of-the-art tools for remediation and enhancement solutions.
Environmental Scan of Moving Image Collections in the United States
With support from The Andrew W. Mellon Foundation, DLF commissioned an environmental scan of traditional moving-image archives, major public and university libraries, museums, and other cultural institutions such as public television broadcasters with significant film and video collections in the United States. The report summarizes which moving-image collections are potentially available for digitization, including a brief enumeration of technical, logistical, organizational, and legal impediments that affect the suitability of these collections for digitization.
Best Practices for OAI PMH Data Provider Implementations and Shareable Metadata: DLF / NSDL Working Group on OAI PMH Best Practices
Sarah L. Shreeves, Jenn Riley, Kat Hagedorn
Supported by DLF and The National Science Digital Library, this publication synthesizes the lessons learned from early adopters of the Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH) and makes recommendations for authoring metadata records that go beyond the basic OAI-PMH requirements to increase the use value of metadata records. Its purpose is to improve communication between library systems.
Metadata Encoding and Transmission Standard: Primer and Reference Manual
Cecilia Preston, Rick Beaubien, Susan Dahl, Nancy Hoebelheinrich, Jerome McDonough, Merrilee Proffitt, and Taylor Surface
As institutions which initially implemented METS have gaine more experience with it, the feasibility of creating useful documentation has been greatly increased. This overiew and tutorial is targeted for especially for prospective users of METS, but will also provide useful information for seasoned developers, metadata analysts, and technical managers.
Contexts and Contributions: Building the Distributed Library
Martha L. Brogan
This publication is a major contribution to the Digital Library Federation's suite of work that focuses on the Open Archives Initiative Protocol for Metadata Harvesting. A compendium piece to the 2003 report A Survey of Digital Library Aggregation Services
, this environmental scan by Martha L. Brogan reveals a maturing and rapidly changing landscape of services. It draws our attention to “major developments affecting the ecosystem of scholarly communications and digital libraries” and provides a rich comparative analysis of digital library aggregation services, including a clear-sighted view of “the obstacles requiring further attention to realize . . . an open, distributed digital library.”
Acquiring Copyright Permission to Digitize and Provide Open Access to Books
by Denise Troll Covey
From the expense and difficulty of determining copyright status and locating the owner to the struggle to get a response from a publisher when seeking permission to digitize for scholarly use, this timely report provides a detailed account of the challenges facing libraries today. It should be of practical use to publishers and librarians alike as we try to navigate the current situation and work to improve it, through such innovations as the "orphaned works" legislation that is currently under discussion. The lessons learned and reported will inform and aid the rest of us as we wrestle with the same problems.
A Kaleidoscope of Digital American Literature
Martha L. Brogan with assistance from Daphnée Rentfrow
This report will be useful to anyone interested in the current state of online American literature resources. Its purpose is twofold: to offer a sampling of the types of digital resources currently available or under development in support of American literature; and to identify the prevailing concerns of specialists in the field as expressed during interviews conducted between July 2004 and May 2005. Part two of the report consolidates the results of these interviews with an exploration of resources currently available. Part three examines six categories of digital work in progress: (1) quality-controlled subject gateways, (2) author studies, (3) public domain e-book collections and alternative publishing models, (4) proprietary reference resources and full-text primary source collections, (5) collections by design, and (6) teaching applications. This survey is informed by a selective review of the recent literature.
Electronic Resource Management: Report of the DLF Electronic Resource Management Initiative.
Timothy D. Jewell, Ivy Anderson, Adam Chandler,
Sharon E. Farb, Kimberly Parker, Angela Riggio, and Nathan D. M. Robertson. (August 2004)
As libraries have worked to incorporate electronic resources into their collections, services, and operations, they have found that their existing integrated library systems are not capable of supporting these new resources. The DLF Electronic Resource Management Initiative was organized to support the rapid development of such systems by producing a series of interrelated documents to define needs and to help establish data standards.
Content and Course Management Systems: Issues of Interoperation.
Report of a study group co-chaired by Dale Flecker, Associate Director for Planning &

Technical Guidelines for Digitizing Archival Materials for Electronic Access: Creation of Production Master Files - Raster Images
Steven Puglia, Jeffrey A. Reed, Erin Rhodes, and the U.S. National Archives and Records Administration. (June 2004)
Archives, libraries, and museums are increasingly building collections of digital surrogates to improve access to their cultural assets. This report addresses a spectrum of considerations for digitizing a variety of works on paper valuable to administrators and technicians alike. Topics include file formats, image capture, metadata, and quality assessment. Although not concerned with preservation reformatting, the guidelines provide a range of options for increasing electronic access to primary source materials.
Archiving Electronic Journals: Research Funded by the Andrew W. Mellon Foundation.
Edited, with an Introduction, by Linda Cantara. (December 2003)
Increasingly, scholarly journals are published electronically. What
does it take to keep them accessible electronically in perpetuity? Can
the property rights of publishers, the access responsibilities of libraries,
and the reliability assurances that scholars need be reconciled in agreements
to create archives of electronic journals? These series of studies from
seven major libraries examine various aspects of the challenges of archiving
electronic journal content.

A Survey of Digital Library Aggregation Services
Martha L. Brogan.
This report, commissioned by DLF, provides an overview of a diverse set of more than thirty digital library aggregation services, organizes them into functional clusters, and then evaluates them more fully from the perspective of an informed user. Most of the services under review rely wholly or partially on the Protocol for Metadata Harvesting of the Open Archives Initiative (OAI-PMH). Each service is annotated with its organizational affiliation, subject coverage, function, audience, status, and size. Critical issues surrounding each of these elements are presented in order to provide the reader with an appreciation of the nuances inherent in seemingly straightforward factual information, such as "audience" or "size."
659 Data Tables for
Dimensions and Use of the Scholarly Information Environment.
We know from anecdotal evidence that users' expectations of
libraries are changing as they find more information directly
from the Web, but anecdotes are an insufficient basis for
developing new library services. DLF and CLIR
commissioned Outsell, Inc. to conduct a
large-scale study to give us a much more reliable picture of user behaviors.
Published here are the
659 data tables that record the responses to 35 groups of questions asked of 3,200
undergraduates, graduate students, and faculty members from academic institutions
ranging from small liberal arts colleges to the largest public and private research universities.
The data tables are available as ICPSR Study No. 20241.

The Digital Library:
A Biography. Daniel Greenstein and Suzanne E. Thorin. (September 2002)
Digital libraries, once project-based and largely autonomous efforts, are maturing.
As individual programs have grown, each has developed its own personality, reflecting
the circumstances of its creation and environment, and its leadership. This report from
CLIR and DLF draws on the results of a survey and case studies of DLF members to
reveal how these influences have molded a range of organizational forms that we call
the digital library. The report is written by Daniel Greenstein and Suzanne Thorin.
Greenstein, formerly the director of DLF, is now university librarian and director
of the California Digital Library. Thorin is the dean of university libraries at
Indiana University. Section one of the report examines three stages of digital
library growth: the young digital library, the maturing digital library, and the
adult digital library. Section two of the report presents case studies of digital
library development at six institutions. [Formats: HTML; PDF; Print]
and Useability Assessment. Library Practices and Concerns.
Denise Troll Covey. (January 2002)
This report offers a survey
of the methods that are being deployed at leading digital
libraries to assess the use and usability of their online
collections and services. Focusing on 24 DLF member libraries, the study's
author, Distinguished DLF Fellow Denise Troll Covey, conducted numerous interviews with
library professionals who are engaged in assessment. The report
describes the application, strengths, and weaknesses of
assessment techniques that include surveys, focus groups, user
protocols, and transaction log analysis. Covey's work is also an
essential methodological guidebook. For each method that she
covers, she is careful to supply a definition, explain why and
how libraries use the method, what they do with the results, and
what problems they encounter. The report includes an extensive
bibliography on more detailed methodological information, and
descriptions of assessment instruments that have proved
particularly effective. [Formats: HTML; PDF; Print]
Work in the Humanities and the Evolving Information
Environment. William S. Brockman, Laura
Neumann, Carole L. Palmer, Tonyia J. Tidline. (December 2001)
As the scholarly information environment changes, so do the needs, expectations,
and behaviors of users. Assessing and responding to those changes
is essential for the academic library so that it may continue in
support of the scholarly mission. The authors of this report have
formally examined how humanities scholars conduct and collate
their research. The study was based on a small sample of
scholars; nonetheless, the results are powerfully suggestive of
ways in which academic libraries can adapt to and develop in a
rapidly changing environment. In particular, the findings
emphasize how important it is for libraries to chart their
evolutionary course in close consultation with scholarly user
communities. This study results from the fruitful
cross-fertilization between the scholar concerned with aspects of
information science and the librarian concerned with delivering
operational information services. [Formats: HTML; PDF; Print]
Strategies for Building Digitized Collections. Abby Smith. (September 2001).
In this report, Abby Smith synthesizes the nearly 10 years' experience that libraries have had digitizing items from their rare, special, and general collections, and making them available online. The learning she uncovers is distilled in and extended by several case studies conducted in leading digital libraries with very different digitization programs. Smith demonstrates that digitization programs work best where their role within a library's collection development strategy is clearly understood, and she identifies several roles that such programs can play. Smith also asks a number of searching questions. She muses about the extent to which digitally reformatted special and rare collections can actually support scholarly research. Probing further, she wonders whether leading research libraries in particular might more usefully focus on digitizing general as opposed to special and rare collections. In this way, they would make important holdings available in new ways while taking a first step in avoiding costs associated with their redundant management. The report is consequently much more than a strategic guide for individual institutions; it is a route map that points important directions for the library community as a whole.

and Presentation of Commercially Available Electronic Resources:
Issues and Practices. Timothy D. Jewell. (July 2001).
report is the second in a series commissioned by DLF to
identify and review digital collection development strategies and
practices. It provides an in-depth look at how several research
libraries select, license, present, and support the use of
commercial online materials. Uncovering a variety of practices,
author Timothy Jewell identifies those that are proving to be
most effective integrating commercial online materials into
library collections. He includes a decision tool that emphasizes
and supports strategic planning, and encourages careful
consideration of how libraries' functions and professional staff
are organized. He also supplies a reference tool, citing working
papers and operational guidelines that libraries rely on but
rarely "publish." Finally, the author frames an important and
practical development agenda by encouraging libraries to
collaborate in designing information systems capable of
organizing the detailed and often dynamic information they need
to maintain about their commercial holdings. [Formats: HTML; PDF; Print]
Sustainable Collections of Free Third-Party Web Resources.
Louis Pitschmann. (June 2001)
This report is the first in a
series commissioned by DLF to identify and review digital
collection development strategies and practices. The report
identifies and synthesizes existing practices used in developing
collections of free third-party Internet resources that support
higher education and research. A review of these practices and
the projects they support confirms that developing collections of
free Web resources is a process that requires its own set of
practices, policies, and organizational models. Where possible,
the report recommends those practices, policies, and models that
have proved to be particularly effective in terms of
sustainability, scalability, cost-effectiveness, and
applicability to their stated purpose. The report outlines the
similarities and differences between print and free Web resources
and describes how the nature and complexity of free Web resources
comply with or challenge traditional library practices and
services pertaining to analog collections. [Formats: HTML; PDF; Print]
Guides to Quality in
Visual Resource Imaging (July 2000).
Five guides issued by DLF and RLG are designed to serve the
growing community of museums, archives, and research libraries
that are turning to digital conversion to provide greater access
to their visual resources as well as to help preserve the
original materials. The guides range from project planning to
scanner selection, considerations for imaging systems, digital
master quality, and masters' storage, and share the experience
and knowledge of leaders in the field. In addition to providing
advice based on the uses to which the images will be put and the
technology now available, they also flag areas where further
research and testing are needed. [Formats: HTML]
