Measurement and Evaluation Of Federated Digital Libraries
Moderator:  Larry Lannom
William Y. Arms, Corporation for National Research Initiatives
Carl Lagoze, Cornell University
Larry Lannom,  CNRI

        The complex world of distributed heterogeneous digital libraries brings with it additional complexity in measurement and
evaluation. Issues to be dealt with include the distributed nature of the digital library, the importance of user interfaces to the system, and the need for systems approaches to deal with heterogeneity amongst the various components of the digital library. In this panel session, these issues are explored from three perspectives.  The work of the D-Lib Working Group on Digital
Library Metrics is discussed (objective: to develop a consensus on usable and useful metrics to evaluate and compare the effectiveness of digital libraries and component technologies in a distributed environment. The D-Lib Test Suite is a group of digital library testbeds that are made available over the Internet for research in digital libraries, information management, collaboration, visualization, and related disciplines. Finally, the Networked Computer Science Technical Reference Library
(NCSTRL) is a confederation of over 100 institutions providing a federated library of computer science material, i.e., a seamless federation of collections and associated library services accessible to the broad community. Evaluation results and lessons from the NCSTRL environment are discussed.

Sponsoring Organization

Environmental decision making, at the policy and resource management levels, require information from a variety of sources that cross public/private sectors and political jurisdictions, and require information from different disciplines in the social, political, and physical sciences.  Data types
include text, museum specimens, remote sensing data, field inventories, and census and economic data. The communities that must interact successfully for optimal decision making have different legacy information systems, different vocabularies, and support a variety of stakeholder groups.  How can these efforts interoperate?  What are the information policy implications? What
efforts are underway?  Using California as an example, this session explores the selection, integration and quality evaluations needed to choose from current and legacy information sources.  The information system requirements are defined.  The coordination across sectors necessary to provide resource managers, policy makers, and other stakeholders with information for environmental decision making is described.  Panelists from the local, state, and national levels will present their experiences, strategies, and perspectives.  The California Environmental Resources Evaluation System (CERES) provides web-based tools and selected information to support resource
managers at the state and local level.  The California Biodiversity Council seeks to coordinate activities across sectors and scientific disciplines in order to improve communication.  California and the U.S. Geological Survey are involved in projects that support the National Biological Information
Infrastructure, a gateway to information and tools that support the exchange and re-use of biodiversity information within the U.S. and internationally. Special emphasis is placed on tools such as a controlled vocabulary that is being jointly developed by CERES and the NBII.  At the national level, projects at the Center for Biological Informatics seek to identify a national research agenda.  The session concludes with a discussion of the research agenda needed to improve the development and evaluation of systems for environmental decision making.

Issues and Methods in Evaluating Federal Websites
Moderator:  Carol A. Hert, Syracuse University

As their websites have grown, agencies have begun to consider the impact of those sites on users, for the organizations and for inter-agency cooperative agreements. This panel will highlight several emerging aspects of website evaluation: how one evaluates website compliance with agency and Federal policy, issues in evaluation which cross agency boundaries, and how one investigates organizational impact of website information and service delivery.  The three panelists all have extensive experience in the evaluation of Federal websites. The  presentations will highlight particular components of those evaluations and offer practical suggestions and techniques for website evaluation.

Panelists:  Charles R. McClure, Syracuse University: Federal Information Policy as a Basis for Evaluating Agency Websites.

An important component of the evaluation of a Federal website is the extent to which it meets Federal Information policy objectives as well as meet policy objectives within the agency.  Dr. McClure, an expert on Federal information policy will discuss the methods employed in a recent website evaluation that employed a policy analysis framework.  Policy issues related to FOIA, the Paperwork Reduction Act, and other initiatives will be considered.

Joanne Silverstein, Information Institute of Syracuse: Understanding the Impact of Websites on Customer Service Activities

Dr. Silverstein is currently engaged in a project concerned with the impacts of websites on customer service activities within a Federal agency.  The existence of the website has brought many new users to the agency as well as new questions, and new ways of accessing agency personnel.  Dr. Silverstein will report on how the agency is evaluating its existing customer service activities and directions it is considering.

Rachel Taylor, U.S. Bureau of the Census: Evaluation of Websites spanning multiple agencies: The Experience of FedStats

FedStats is a locator website designed to facilitate access to Federal statistical agencies and information.  Unlike many national statistical systems, the United States environment is characterized by numerous agencies (over 70) which have responsibilities to produce and disseminate statistics.  Designing and evaluating a website representing multiple agencies presents unique challenges. Ms. Taylor, who has been involved with FedStats design and evaluation will report on some of these challenges and strategies for addressing.

Use, Users, and Using the Internet – A research perspective on the users of  networked information resources and services

The rising level of general public and professional access to networked information resources and services has produced a fertile proving ground for user-oriented information researchers. For some time now, the user-oriented paradigm has been regarded as a mainstream research framework for information science. This paradigm has guided our thinking about information systems, services and resource throughout the 1990s – focusing the attention of our research on the people who use information, what they use it for and how they use it. The three papers presented in this session are research based. They focus on use, users and using the Internet and provide a collective insight into the way that networked information resources are serving the information needs of professions and the professional needs of practitioners. All three papers are presented by researchers from the School of Library and Information Science at the University of Washington. 

Web Searching Behavior of Engineers
Raya Fidel and Efthimis Efthimiadis
School of Library and Information Science
University of Washington

What are the major patterns of Web searching among engineers, and how effective are they?  A work-centered framework guided a study that interviewed and observed nine engineers as they were performing their regular, job-related searches, each for about three searches.  All participants found Web searching important to their work, and their searches involved a great deal of planning, selection of information sources, and identification of information needs.  From among the mental strategies available to them, the engineers most frequently selected browsing and the analytical strategy, yet only less than a half of the searches were completed successfully, and 20% came to a dead-end. The results suggest that improved design of information systems for the engineers could be achieved by providing support for locating experts and potential collaborators, using search syntax, using mental strategies, browsing results pages, selection of information sources and planning.  Further, searching will become easier and more fruitful with a well-designed structure for navigation.

What do we know about academic users
Harry Bruce
School of Library and Information Science
University of Washington

This paper traces a research program of five research studies that aimed to find out how academics and researchers use the resources and services of the Internet to help them do their work. The studies cover a range of methods and approaches and include a case study, exploratory study, longitudinal study, quantitative study and a study that focused on information searching behavior. The period of these studies spans the past seven years and provides a historical and empirical perspective on use and using of the Internet by a professional group who are arguably the keenest stakeholders in the development of networked information resources and services. The paper answers several questions --  What do we know now? Has a user perspective on the Internet helped us to understand its development and impact? What don’t we know and how can we find out more?

The Emergence of the Web as a Reference Resource & Tool:  Initial Empirical Results
Joseph Janes
School of Library and Information Science
University of Washington

Librarians, particularly reference librarians, have always adopted and adapted new technologies for their purposes, both as resources for meeting information needs but also as methods for communication and practice.  The Web is, of course, the most recent innovation to be enfolded into practice.  This paper will draw on three sets of empirical findings:  a prior study comparing reference performance using Web and non-Web resources, and two pilot studies for larger investigations, one on the number and kinds of libraries which are conducting reference services via the Web, and one examining characteristics of questions and answering practice of a mature digital reference service.  These findings will help us to better understand the current state of use and practice and give some indications to potential future applications and uses of networked resources.

Many organizations are deploying or actively considering implementing the ANSI/NISO Z39.50
Information Retrieval Protocol in networked information discovery and retrieval (NIDR) projects. Diverse communities including cultural heritage and natural history museums, earth observation
data projects, and others are using Z39.50 for search and retrieval applications — applications well beyond the library/bibliographic domain from which the standard emerged. Z39.50 is perceived as an important technical and strategic tool for NIDR and for providing users integrated access to distributed resources. Now, after more than six years of production-level experience with Z39.50, organizations and projects are beginning to conduct systematic evaluation studies of Z39.50 implementation and usability. In 1998, three major Z39.50 initiatives underwent evaluation. This panel addresses findings from recent Z39.50 evaluation studies and suggests strategies to inform the
successful planning, development, and future deployment of Z39.50.

This panel consists of four presentations:

1. The State Library of Iowa is using Z39.50 to interconnect many libraries; online catalogs through its SILO (State of Iowa Library Online) Project. Blue Angel Technologies, a leading Z39.50 product developer and vendor, conducted an evaluation of SILO and released its report in May 1998. On behalf of Blue Angel Technologies, William Moen presents significant findings of the study. For reference, see:

2. For the past two years, the National Library of Canada has led an initiative to develop a virtual
Canadian union catalog (vCuc). Carrol Lunau, project director of vCuc, summarizes issues and challenges of Z39.50 use across multiple sites based upon several evaluation efforts during the
vCuc effort. For reference, see:

3. A third evaluation study conducted by Mark Hinnebusch (chair of the international Z39.50 Implementors Group) examined the Z39.50 utility to support the Virtual Electronic Library of the Big Ten universities and the University of Chicago. Charlene Mason, Deputy University Librarian for the Univerity of Minnesota Libraries, discusses this evaluation and its resulting recommendations. For reference, see:

4. Moen concludes the presentations by discussing the Z Texas Project, a new statewide initiative to
build upon existing Z39.50 experiences and utilize the evaluation studies; results to plan both strategic and tactical approaches to address challenges of Z39.50 interoperability among Texas libraries.

Attendees will learn about the current status of several important Z39.50 implementations. In addition, these projects provide a lens on the complex challenges of networked discovery and retrieval across distributed resources. More importantly, the panel presentations suggest evaluation
techniques for understanding complex and inter-related technology deployments such as Z39.50-accessible databases. Finally, the panel demonstrates the importance of ongoing evaluation of technologies such as Z39.50 to expose and define interoperability problems in networked information discovery and retrieval. Evaluation findings can aid in the creation of new solutions and
pathways to successful technology implementations.

This session will outline the findings of the Mellon-sponsored study of digital image distribution
focusing on the Museum Educational Site Licensing Project (MESL). In the MESL project seven
repositories supplied an identical set of 10,000 images and accompanying descriptive metadata to
seven universities, and each university mounted this information within their own customized delivery
system. This Mellon-sponsored study evaluated the costs, infrastructure, and efforts involved in
implementing the MESL project, as well as user reaction to functionality. The study also examined
costs of running analog slide libraries and compared these to costs and functionality associated with
digital image distirbution.

Panelists will discuss the cost-center models used to examine the distribution of digital and analog
images, including: creating digital images and metadata, mounting and distributing digital images,
maintaining a distribution house, running a slide library, and an analysis of hybrid image libraries.
They will present a comparison of user interfaces and search engines from the MESL universities.
They will also report on the results of focus groups discussing faculty adoption of digital images for
classroom use.

Major findings include:

     It will be a long time before digital image repositories will be able to deliver the
     critical mass of images needed for instruction and research. Analog slide libraries and
     digital image repositories will necessarily coexist for many years.
     The higher education community is enthusiastic about providing access to digital
     images and information from cultural heritage repositories. However, many
     impediments to widespread adoption must be dealt with—ranging from lack of
     comprehensive content and the absence of necessary tools to facilitate use, to inadequate
     recognition and support for faculty who adopt new technology in their teaching.
     The anticipated shift from analog slide libraries to licensed digital images represents
     a shift from ownership to access through ongoing subscription. This shift is analogous
     to the changes that have taken place in university library collections. University administrators
     are concerned about controlling content costs and faculty are concerned about ongoing
     access to the images they use and need. Those university positions are at odds with those of
     museum image distribution consortia, who seek a consistent revenue stream and are reluctant
     to assure ongoing access without ongoing payment. For such image distribution schemes to
     work, both museums and universities have to see their common goals as outweighing their
     individual concerns.

Implications of the Production, Distribution, and Usage of Image Data is available at

There are research findings and anecdotal evidence to suggest significant changes in the information behavior of professionals who have ready access to databases and full text resources.  Panelists in this session will describe the ways in which
individuals in the classical  professions of medicine, law, and ministry)  access and use information, with particular emphasis on how use patterns have changed with the introduction and assimilation of technology. These professions vary significantly in the types of resources used and the amount of time that resources have been automated, ranging from law, automated in the early 1970's, to the much more recently automated divinity profession.  Desirable outcomes of this session include cross-disciplinary
fertilization and perhaps the development of hypotheses generalizable beyond a single profession.

The panel includes presentations by practitioners and researchers in thethree professions.  With the help of a discussant, a reference-oriented academic, the panel and the audience will then be able to compare and contrast information behaviors across the professions.

Community networks (CNs) are computer-based services designed to provide online information resources and communication tools to residents of a particular geographic region. CNs are a relatively new "genre" of information system, which raises special problems in assessing user needs
and outcomes. Nonetheless, societal outcomes related to CNs possess particular importance for LIS. Of special significance is the role that CNs play in reducing the "digital divide" that currently separates haves and have nots in the information age. In addition, a natural alliance exists between the goals and services of CNs and public libraries, and a number of public libraries are, in fact, major partners in their local CN initiatives.

Evaluation is only possible when observable activities are linked to goals and objectives. For many reasons, evaluating a new public institution like CNs is a daunting task. Since the goals are ambitious and wide-ranging, they are unlikely to be realized in the short term. Nor are they likely to be realized through the efforts of community networks alone in the absence of other societal assistance or individual effort.

The proposed panel will both describe efforts to evaluate the use and impact of CNs and discuss conceptual and methodological issues in this realm. They draw on their own experiences in CN research, including a study of the role of public libraries within the landscape of community help giving, participatory action research related to community problem-solving, and a study of CN needs and uses in low-income neighborhoods.

Panelists will consider the role and contribution of various data collection methods, including online surveys, transaction logging (the automatic logging of usage data by CN system servers), in-depth
interviews, structured observation, and focus groups. The utilization of evaluation results will be addressed, including the development of impact indicators, descriptions of best practices, and recommendations for outreach and training.

Among the issues panelists will discuss are the following:

--      Conceptual problems that attend the word community, and different ways of putting a networking project into a larger analytical context;

--      Conceptual issues in using sense-making theory to study the social construction and use of community information in online environments;

--      The need to study specific incidents of citizens' information behavior in context of their social worlds and, more specifically, the perceptions and expectations of other key players (e.g., service
providers, search intermediaries);

--      The need to develop a "family" of goals (including broad goals of societal meliorism) for CNs, in order to construct a broad-based picture of how effective community networks are in meeting the needs of the community they serve;

--      Common links between CNs and other system genres, such as digital libraries, in evaluation research.

--      Challenges inherent in managing and making sense of system logs, from dealing with millions of log entries to moving from log data to direct indicators of users' intents, desires or disappointments.

The World Wide Web (Web) represents the most conspicuous instance of networked information resources today. While the Web is mushrooming before our eyes, little is known about evaluation of Web-based information from the perspective of financial management. This management encompasses both the information provider and information user perspective, in both the intra- and extra-organizational context.

From the information provider perspective, some of the relevant questions are: What are the tangible and intangible costs and benefits of Web-based-information? What are the direct and indirect costs of maintaining Web-based information? How do these expenditures compare with those pertaining to an equivalent print source? What are the hidden costs of maintaining Web-based information, such as the conversion from one technology to another? What are the methods of estimating benefits from
Web-based information; of  return on investment? From the information user perspective, relevant questions also include issues of tangible and intangible costs and benefits of Web-based-information? In addition, What methods can be used for assessing value of internal Web-based-information? Are there attempts of using newer valuing methodologies (e.g., total value, and value-in-use)?

The panel will host practitioners from several organizations. An example of using return on investment analysis in the process of technology conversion  of organizational memory at Intel Corporation will be discussed. In addition, examined will be the issues and experiences in the management of electronic information at New York Public Library.  Moreover, the use of cost/benefit analysis at the virtual library of California Institute of Technology will be presented.

Commercial database access vendors have recently shifted to graphical user interfaces and web page formats.  The traditional text based interface, while still an alternative, may soon fall to the way side as the appeal of web/graphical interfaces continues to increase.  However, users of these vendored database products are not all in agreement about the actual appeal and
usefulness of the new interfaces.  To gain insight into the evaluation of network interfaces and the decision criteria employed by the vendors, this open forum discussion of specific questions poised to the vendors prior to the meeting will provide a basis for informal discussion with the audience.

 Hahn will present a brief historical background on interface design decisions of the 60s and 70s and how users reacted to them.  This will set the stage for  Pliske of LEXIS-NEXIS and  Pryor of Dialog to discuss how their companies determine what the network interfaces should look like and what methods of evaluation and feedback they use to support these decisions.
They will also discuss how they envision the future of these types of access systems in light of the network communication evolution.

Using networked information resources and services today increasingly involves controlling access to licensed databases or student coursework and course materials. This control requires some method of first identifying positively who the requester is (authentication) and ensuring that they are allowed to enter that resource (authorization). What are the options for accomplishing this control? How are libraries, instructors, and the university community handling this challenge? Our overview presenter,
Clifford Lynch, will outline the issues involved and describe several national initiatives studying this issue, including the Coalition for Network Information's White Paper on Authentication and Authorization. Sal Gurnani from the California Digital Library will talk about their project working with OCLC and JSTOR to pilot the use of X.509 client certificates in conjunction with a directory interface to authenticate individuals and authorize access to licensed content on publisher web sites.
