Ronald LARSEN Directions in High-Performance Networking for Libraries
The pace at which computing technology has advanced over the past forty years shows no sign of abating. Roughly speaking, each five-year period has yielded an order-of-magnitude improvement in price and performance of computing equipment. No fundamental hurdles are likely to prevent this pace from continuing for at least the next decade. It is only in the past five years, though, that computing has become ubiquitous in libraries, affecting all staff and patrons, directly or indirectly.
During these same five years, communications rates on the Internet, the principal academic computing network, have grown from 56 kbps to 1.5 Mbps, and the NSFNet backbone is now running 45 Mbps. Over the next five years, communication rates on the backbone are expected to exceed 1 Gbps. Growth in both the population of network users and the volume of network traffic has continued to grow geometrically, at rates approaching 15 percent per month. This flood of capacity and use, likened by some to "drinking from a firehose," creates immense opportunities and challenges for libraries. Libraries must anticipate the future implications of this technology, participate in its development, and deploy it to ensure access to the world's information resources.
The infrastructure for the information age is being put in place. Libraries face strategic decisions about their role in the development, deployment, and use of this infrastructure. The emerging infrastructure is much more than computers and communication lines. It is more than the ability to compute at a remote site, send electronic mail to a peer across the country, or move a file from one library to another. The next five years will witness substantial development of the information infrastructure of the network.
In order to provide appropriate leadership, library professionals must have a fundamental understanding of and appreciation for computer networking, from local area networks to the National Research and Education Network (NREN). This presentation addresses these fundamentals, and how they relate to libraries today and in the near future.
Edwin BROWNRIGG Electronic Library Visions and Realities
The electronic library has been a vision desired by many—and rejected by some—since Vannevar Bush coined the term memex to describe an automated, intelligent, personal information system. Variations on this vision have included Ted Nelson's Xanadau, Alan Kay's Dynabook, and Lancaster's "paperless library," with the most recent incarnation being the "Knowledge Navigator" described by John Scully of Apple. But the reality of library service has been less visionary and the leap to the electronic library has eluded universities, publishers, and information technology files.
The Memex Research Institute (MemRI), an independent, nonprofit research and development organization, has created an Electronic Library Program of shared research and development in order to make the collective vision more concrete. The program is working toward the creation of large, indexed publicly available electronic image collections of published documents in academic, special, and public libraries. This strategic plan is the result of the first stage of the program, which has been an investigation of the information technologies available to support such an effort, the economic parameters of electronic service compared to traditional library operations, and the business and political factors affecting the shift from print distribution to electronic networked access.
The strategic plan envisions a combination of publicly searchable access databases, image (and text) document collections stored on network "file servers," local and remote network access, and an intellectual property management-control system. This combination of technology and information content is defined in this plan as an E-library or E-library collection. Some participating sponsors are already developing projects based on MemRI's recommended directions.
The E-library strategy projected in this plan is a visionary one that can enable major changes and improvements in academic, public, and special library service. This vision is, though, one that can be realized with today's technology. At the same time, it will challenge the political and social structure within which libraries operate: in academic libraries, the traditional emphasis on local collections, extending to accreditation issues; in public libraries, the potential of electronic branch and central libraries fully available to the public; and for special libraries, new opportunities for shared collections and networks.
The environment in which this strategic plan has been developed is, at the moment, dominated by a sense of library limits. The continued expansion and rapid growth of local academic library collections is now clearly at an end. Corporate libraries, and even law libraries, are faced with operating within a difficult economic climate, as well as with very active competition from commercial information sources. For example, public libraries may be seen as a desirable but not critical municipal service in a time when the budgets of safety and health agencies are being cut back.
Further, libraries in general have a very high labor-to-cost ratio in their budgets, and labor costs are still increasing, notwithstanding automation investments. It is difficult for libraries to obtain capital, startup, or seed funding for innovative activities, and those technology-intensive initiatives that offer the potential of decreased labor costs can provoke the opposition of library staff.
However, libraries have achieved some considerable successes in the past two decades by improving both their service and their credibility within their organizations—and these positive changes have been accomplished mostly with judicious use of information technologies. The advances in computing and information technology have been well-chronicled: the continuing precipitous drop in computing costs, the growth of the Internet and private networks, and the explosive increase in publicly available information databases.
For example, OCLC has become one of the largest computer network organizations in the world by creating a cooperative cataloging network of more than 6,000 libraries worldwide. On-line public access catalogs now serve millions of users on more than 50,000 dedicated terminals in the United States alone. The University of California MELVYL on-line catalog system has now expanded into an index database reference service and supports more than six million searches a year. And, libraries have become the largest group of customers of CD-ROM publishing technology; more than 30,000 optical media publications such as those offered by InfoTrac and Silver Platter are subscribed to by U.S. libraries.
This march of technology continues and in the next decade will result in further innovations that are extremely difficult to predict. What is clear is that libraries can now go beyond automation of their order files and catalogs to automation of their collections themselves—and it is possible to circumvent the fiscal limitations that appear to obtain today.
This Electronic Library Strategic Plan recommends a paradigm shift in library service, and demonstrates the steps necessary to provide improved library services with limited capacities and operating investments.

The Cornell/Xerox Joint Study in Digital Preservation resulted in the recording of 1,000 brittle books as 600-dpi digital images and the production, on demand, of high-quality and archivally sound paper replacements. The project, which was supported by the Commission on Preservation and Access, also investigated some of the issues surrounding scanning, storing, retrieving, and providing access to digital images in a network environment.
Anne Kenney will focus on some of the issues surrounding direct scanning as identified in the Cornell Xerox Project. Among those to be discussed are: image versus text capture; indexing and access; image-capture capabilities; a comparison to photocopy and microfilm; production and cost analysis; storage formats, protocols, and standards; and the use of this scanning technology for preservation purposes.
The 600-dpi digital images produced in the Cornell Xerox Project proved highly acceptable for creating paper replacements of deteriorating originals. The 1,000 scanned volumes provided an array of image-capture challenges that are common to nineteenth-century printing techniques and embrittled material, and that defy the use of text-conversion processes. These challenges include diminished contrast between text and background, fragile and deteriorated pages, uneven printing, elaborate type faces, faint and bold text adjacency, handwritten text and annotations, nonRoman languages, and a proliferation of illustrated material embedded in text. The latter category included high-frequency and low-frequency halftones, continuous tone photographs, intricate mathematical drawings, maps, etchings, reverse-polarity drawings, and engravings.
The Xerox prototype scanning system provided a number of important features for capturing this diverse material. Technicians used multiple threshold settings, filters, line art and halftone definitions, autosegmentation, windowing, and software-editing programs to optimize image capture. At the same time, this project focused on production. The goal was to make scanning as affordable and acceptable as photocopying and microfilming for preservation reformatting. A time-and-cost study conducted during the last three months of this project confirmed the economic viability of digital scanning, and these findings will be discussed here.
From the outset, the Cornell Xerox Project was predicated on the use of nonproprietary standards and the use of common protocols when standards did not exist. Digital files were created as TIFF images which were compressed prior to storage using Group 4 CCITT compression. The Xerox software is MS DOS based and utilizes off-the shelf programs such as Microsoft Windows and Wang Image Wizard. The digital library is designed to be hardware-independent and to provide interchangeability with other institutions through network connections. Access to the digital files themselves is two-tiered: Bibliographic records for the computer files are created in RLIN and Cornell's local system and access into the actual digital images comprising a book is provided through a document control structure and a networked image file-server, both of which will be described.
The presentation will conclude with a discussion of some of the issues surrounding the use of this technology as a preservation tool (storage, refreshing, backup).
Pamela ANDRE and Judith ZIDAR
The National Agricultural Library (NAL) has had extensive experience with raster scanning of printed materials. Since 1987, the Library has participated in the National Agricultural Text Digitizing Project (NATDP) a cooperative effort between NAL and forty-five land grant university libraries. An overview of the project will be presented, giving its history and NAL's strategy for the future.
An in-depth discussion of NATDP will follow, including a description of the scanning process, from the gathering of the printed materials to the archiving of the electronic pages. The type of equipment required for a stand-alone scanning workstation and the importance of file management software will be discussed. Issues concerning the images themselves will be addressed briefly, such as image format; black and white versus color; gray scale versus dithering; and resolution.
Also described will be a study currently in progress by NAL to evaluate the usefulness of converting microfilm to electronic images in order to improve access. With the cooperation of Tuskegee University, NAL has selected three reels of microfilm from a collection of sixty-seven reels containing the papers, letters, and drawings of George Washington Carver. The three reels were converted into 3,500 electronic images using a specialized microfilm scanner. The selection, filming, and indexing of this material will be discussed.

Project Open Book, the Yale University Library's effort to convert 10, 000 books from microfilm to digital imagery, is currently in an advanced state of planning and organization. The Yale Library has selected a major vendor to serve as a partner in the project and as systems integrator. In its proposal, the successful vendor helped isolate areas of risk and uncertainty as well as key issues to be addressed during the life of the project. The Yale Library is now poised to decide what material it will convert to digital image form and to seek funding, initially for the first phase and then for the entire project.
The proposal that Yale accepted for the implementation of Project Open Book will provide at the end of three phases a conversion subsystem, browsing stations distributed on the campus network within the Yale Library, a subsystem for storing 10,000 books at 200 and 600 dots per inch, and network access to the image printers. Pricing for the system implementation assumes the existence of Yale's campus ethernet network and its high-speed image printers, and includes other requisite hardware and software, as well as system integration services. Proposed operating costs include hardware and software maintenance, but do not include estimates for the facilities management of the storage devices and image servers.
Yale selected its vendor partner in a formal process, partly funded by the Commission for Preservation and Access. Following a request for proposal, the Yale Library selected two vendors as finalists to work with Yale staff to generate a detailed analysis of requirements for Project Open Book. Each vendor used the results of the requirements analysis to generate and submit a formal proposal for the entire project. This competitive process not only enabled the Yale Library to select its primary vendor partner but also revealed much about the state of the imaging industry, about the varying, corporate commitments to the markets for imaging technology, and about the varying organizational dynamics through which major companies are responding to and seeking to develop these markets.
Project Open Book is focused specifically on the conversion of images from microfilm to digital form. The technology for scanning microfilm is readily available but is changing rapidly. In its project requirements, the Yale Library emphasized features of the technology that affect the technical quality of digital image production and the costs of creating and storing the image library: What levels of digital resolution can be achieved by scanning microfilm? How does variation in the quality of microfilm, particularly in film produced to preservation standards, affect the quality of the digital images? What technologies can an operator effectively and economically apply when scanning film to separate two-up images and to control for and correct image imperfections? How can quality control best be integrated into digitizing work flow that includes document indexing and storage?
The actual and expected uses of digital images—storage, browsing, printing, and OCR—help determine the standards for measuring their quality. Browsing is especially important, but the facilities available for readers to browse image documents is perhaps the weakest aspect of imaging technology and most in need of development. As it defined its requirements, the Yale Library concentrated on some fundamental aspects of usability for image documents: Does the system have sufficient flexibility to handle the full range of document types, including monographs, multi-part and multivolume sets, and serials, as well as manuscript collections? What conventions are necessary to identify a document uniquely for storage and retrieval? Where is the database of record for storing bibliographic information about the image document? How are basic internal structures of documents, such as pagination, made accessible to the reader? How are the image documents physically presented on the screen to the reader?
The Yale Library designed Project Open Book on the assumption that microfilm is more than adequate as a medium for preserving the content of deteriorated library materials. As planning in the project has advanced, it is increasingly clear that the challenge of digital image technology and the key to the success of efforts like Project Open Book is to provide a means of both preserving and improving access to those deteriorated materials.
SESSION IV-B
George THOMA
In the use of electronic imaging for document preservation, there are several issues to consider, such as: ensuring adequate image quality, maintaining substantial conversion rates (through-put), providing unique identification for automated access and retrieval, and accommodating bound volumes and fragile material.
To maintain high image quality, image processing functions are required to correct the deficiencies in the scanned image. Some commercially available systems include these functions, while some do not. The scanned raw image must be processed to correct contrast deficiencies— both poor overall contrast resulting from light print and/or dark background, and variable contrast resulting from stains and bleed-through. Furthermore, the scan density must be adequate to allow legibility of print and sufficient fidelity in the pseudo-halftoned gray material. Borders or page-edge effects must be removed for both compactibility and aesthetics. Page skew must be corrected for aesthetic reasons and to enable accurate character recognition if desired. Compound images consisting of both two-toned text and gray-scale illustrations must be processed appropriately to retain the quality of each.

Standards publications being developed by scientists, engineers, and business managers in Association for Information and Image Management (AIIM) standards committees can be applied to electronic image management (EIM) processes including: document (image) transfer, retrieval and evaluation; optical disk and document scanning; and document design and conversion. When combined with EIM system planning and operations, standards can assist in generating image databases that are interchangeable among a variety of systems. The applications of different approaches for image-tagging, indexing, compression, and transfer often cause uncertainty concerning EIM system compatibility, calibration, performance, and upward compatibility, until standard implementation parameters are established. The AIIM standards that are being developed for these applications can be used to decrease the uncertainty, successfully integrate imaging processes, and promote "open systems." AIIM is an accredited American National Standards Institute (ANSI) standards developer with more than twenty committees comprised of 300 volunteers representing users, vendors, and manufacturers. The standards publications that are developed in these committees have national acceptance and provide the basis for international harmonization in the development of new International Organization for Standardization (ISO) standards.
This presentation describes the development of AIIM's EIM standards and a new effort at AIIM, a database on standards projects in a wide framework of imaging industries including capture, recording, processing, duplication, distribution, display, evaluation, and preservation. The AIIM Imagery Database will cover imaging standards being developed by many organizations in many different countries. It will contain standards publications' dates, origins, related national and international projects, status, key words, and abstracts. The ANSI Image Technology Standards Board requested that such a database be established, as did the ISO/International Electrotechnical Commission Joint Task Force on Imagery. AIIM will take on the leadership role for the database and coordinate its development with several standards developers.
Patricia BATTIN
Characteristics of standards for digital imagery:
* Nature of digital technology implies continuing volatility.
* Precipitous standard-setting not possible and probably not desirable.
* Standards are a complex issue involving the medium, the hardware, the software, and the technical capacity for reproductive fidelity and clarity.
* The prognosis for reliable archival standards (as defined by librarians) in the foreseeable future is poor.
Significant potential and attractiveness of digital technology as a preservation medium and access mechanism.
Productive use of digital imagery for preservation requires a reconceptualizing of preservation principles in a volatile, standardless world.
Concept of managing continuing access in the digital environment rather than focusing on the permanence of the medium and long-term archival standards developed for the analog world.
Transition period: How long and what to do?
* Redefine "archival."
* Remove the burden of "archival copy" from paper artifacts.
* Use digital technology for storage, develop management strategies for refreshing medium, hardware and software.
* Create acid-free paper copies for transition period backup until we develop reliable procedures for ensuring continuing access to digital files.

Stuart WEIBEL The Role of SGML Markup in the CORE Project (6)
The emergence of high-speed telecommunications networks as a basic feature of the scholarly workplace is driving the demand for electronic document delivery. Three distinct categories of electronic publishing/republishing are necessary to support access demands in this emerging environment:
1.) Conversion of paper or microfilm archives to electronic format 2.) Conversion of electronic files to formats tailored to electronic retrieval and display 3.) Primary electronic publishing (materials for which the electronic version is the primary format)
OCLC has experimental or product development activities in each of these areas. Among the challenges that lie ahead is the integration of these three types of information stores in coherent distributed systems.
The CORE (Chemistry Online Retrieval Experiment) Project is a model for the conversion of large text and graphics collections for which electronic typesetting files are available (category 2). The American Chemical Society has made available computer typography files dating from 1980 for its twenty journals. This collection of some 250 journal-years is being converted to an electronic format that will be accessible through several end-user applications.
The use of Standard Generalized Markup Language (SGML) offers the means to capture the structural richness of the original articles in a way that will support a variety of retrieval, navigation, and display options necessary to navigate effectively in very large text databases.
An SGML document consists of text that is marked up with descriptive tags that specify the function of a given element within the document. As a formal language construct, an SGML document can be parsed against a document-type definition (DTD) that unambiguously defines what elements are allowed and where in the document they can (or must) occur. This formalized map of article structure allows the user interface design to be uncoupled from the underlying database system, an important step toward interoperability. Demonstration of this separability is a part of the CORE project, wherein user interface designs born of very different philosophies will access the same database.
NOTES: (6) The CORE project is a collaboration among Cornell University's Mann Library, Bell Communications Research (Bellcore), the American Chemical Society (ACS), the Chemical Abstracts Service (CAS), and OCLC.
Michael LESK The CORE Electronic Chemistry Library
A major on-line file of chemical journal literature complete with graphics is being developed to test the usability of fully electronic access to documents, as a joint project of Cornell University, the American Chemical Society, the Chemical Abstracts Service, OCLC, and Bellcore (with additional support from Sun Microsystems, Springer-Verlag, DigitaI Equipment Corporation, Sony Corporation of America, and Apple Computers). Our file contains the American Chemical Society's on-line journals, supplemented with the graphics from the paper publication. The indexing of the articles from Chemical Abstracts Documents is available in both image and text format, and several different interfaces can be used. Our goals are (1) to assess the effectiveness and acceptability of electronic access to primary journals as compared with paper, and (2) to identify the most desirable functions of the user interface to an electronic system of journals, including in particular a comparison of page-image display with ASCII display interfaces. Early experiments with chemistry students on a variety of tasks suggest that searching tasks are completed much faster with any electronic system than with paper, but that for reading all versions of the articles are roughly equivalent.
Pamela ANDRE and Judith ZIDAR
Text conversion is far more expensive and time-consuming than image capture alone. NAL's experience with optical character recognition (OCR) will be related and compared with the experience of having text rekeyed. What factors affect OCR accuracy? How accurate does full text have to be in order to be useful? How do different users react to imperfect text? These are questions that will be explored. For many, a service bureau may be a better solution than performing the work inhouse; this will also be discussed.

Copyright law protects creative works. Protection granted by the law to authors and disseminators of works includes the right to do or authorize the following: reproduce the work, prepare derivative works, distribute the work to the public, and publicly perform or display the work. In addition, copyright owners of sound recordings and computer programs have the right to control rental of their works. These rights are not unlimited; there are a number of exceptions and limitations.
An electronic environment places strains on the copyright system. Copyright owners want to control uses of their work and be paid for any use; the public wants quick and easy access at little or no cost. The marketplace is working in this area. Contracts, guidelines on electronic use, and collective licensing are in use and being refined.
Issues concerning the ability to change works without detection are more difficult to deal with. Questions concerning the integrity of the work and the status of the changed version under the copyright law are to be addressed. These are public policy issues which require informed dialogue.
