The NSDL Search Service
September 2002-- A third grade teacher who holds an MAT in Education is looking for materials to include in lesson plans. He/she has experience using Internet search engines. Will the NSDL Search Service deliver? Whether users are experts or novices, the NSDL Search Service enables a third grade teacher to make a quick stop for targeted materials, or for others to take thought-provoking strolls through rich science resources. Discovery in the NSDL is focused on leveraging the user's knowledge against the added capabilites of a large, growing, dynamic, and distributed aggregation of learning resources. Users will ask for and get specific types and formats of items and collections. Three levels of searching are available: a simple search box that will always appear in the main portal, a basic search with filters, and an advanced search with boolean capabilities. The solid underlying technology that supports the NSDL Search Service is designed to scale up to accomodate a very large volume of data, eventually matching many thousands of users with millions of catalog records. Additional search services will be part of NSDL in the future. While the first version of NSDL Search is a general discovery tool, other search service providers may use access to the metadata repository to focus on discovery of specific information from the NSDL catalog, amplifying the Library's ability to meet user needs in ways that have not yet been imagined. Testing of the NSDL Search Service will begin next month.
Please Comment on Emerging Metadata Policy for the NSDL
September 2002-- Len Simutis, Eisenhower National Clearinghouse, and Stuart A. Sutton, University of Washington, and the NSDL Policy Committee, and William Arms and Diane Hillmann, Cornell, and the Core Integration team, have worked with the NSDL Policy Committee to create a draft of a "Metadata Policy for the NSDL." Public comment and discussion is encouraged on "PC-3" until September 24. Based on comments received by then, the NSDL Policy Committee will review the [NSDL Metadata Policy (PC-3)] for possible action at its meeting on Sept. 29 at the site of the MERLOT Conference in Atlanta. Metadata plays a key role in the collection development activities of the NSDL. It is of particular importance to have a policy that clarifies NSDL assumptions and plans regarding metadata. The NSDL community is encouraged to read and comment on this critical document which can be found at http://policy.comm.nsdlib.org/docs/.

CI Executives Participate in Library Cognitive Walk-throughs
September 2002-- On August 20 members of the CI Executive Group took part in cognitive walk-throughs of the Search and Browse components of the new Library in the Cornell Information Science Usability Lab. In preparation for these excercises the Cornell CI Portals/UI team met with Tammy Sumner, NSDL Educatonal Impact and Evaluation Standing Comm. chair, earlier in the summer to plan for evaluation of the NSDL system. She suggested that cognitive walk-throughs and heuristic evaluations be conducted to inform development. The Cornell CI Portals/UI team has developed and conducted cognitive walk-throughs of Library components internally and with partners as part of an ongoing iterative design process. Documentation can be found at http://portals.comm.nsdlib.org/cgi-bin/wiki.pl?MtgMin and in "Primary Documents" at http://portals.comm.nsdlib.org/cgi-bin/wiki.pl?User_Interface_and_Portals. Geri Gay, Director, Cornell HCI Group, Vivian Evangelista, PhD? student in education, Cornell, and John Efroymson, third grade teacher, NYS Spencer-Van Etten School District, assisted in developing user profiles, scenarios, tasks, and reporting forms for this exercise. Similar cognitive walk-throughs will be conducted with potential users including librarians and teachers this fall. Results will be available online.

Diversity & Accessibility Workspace
September 2002-- A new workspace is now available on the NSDL Communications Portal devoted to addressing issues of Diversity and Accessibility in digital library development and use http://diversity.comm.nsdlib.org. This workspace is a collaborative effort headed by Sarita Nair, Director of the [Gender & Science Digital Library Project] at Education Development Center, Inc. (EDC), Rachel Bower, Director of the [Internet Scout Project] from the University of Wisconsin, Madison, and Edward Almasy, Technical Director of the Internet Scout Project. This Diversity & Accessibility workspace is aimed at disseminating information and encouraging dialogue amongst NSDL projects to ensure full access of the NSDL to all users - regardless of disability, economic situation, race, ethnicity or geographic location. It will support the development of resources and discussions on a wide range of issues to help the NSDL community meet the needs of users with disabilities, reduce and eliminate gender/diversity barriers in STEM education, and encourage full use of the NSDL by all. Involvement from all is necessary to make this forum an effective and useful place. Readers are also encouraged to submit to the Projects, Resources, and Events sections.

NSDL Publishers Workshop on Oct. 8
September 2002-- Over the next year or two it will be critical for NSDL to begin to integrate proprietary content into its distributed collections, and also to consider possible relationships between NSDL and for-profit libraries. Several NSDL projects have begun to forge tentative connections with publishers. However, one practical near-term step for NSDL as a whole is to convene a workshop on these issues, collecting together current insights, and bringing to the table a number of the publishers with whom individual projects are now working. The Workshop agenda is being developed. Please visit http://comm.nsdlib.org/forum/forum.php?forum_id=253 to read the Publishers Workshop planning documents by Dave McArthur?, Collegis, or email [Dave] for more information.

Special Session on Digital Libraries at GSA 2002
September 2002-- A special session on digital libraries is scheduled for the [2002 Annual Meeting of the American Geological Society] (AGS) in Denver. Session #199: [Digital Libraries as Vehicles for Systemic Educational Change] will be co-chaired by Mary Marlino (DLESE Program Center); Cathy Manduca (Carleton College), and Ed Geary (Colorado State University), and is sponsored by the [National Association of Geoscience Teachers] (NAGT). The session will be held on October 30 (8:15 AM ? 12:00 PM) with a variety of presentations designed to inform educators of innovative resources and issues that enhance pedagogical effectiveness and encourage educational reform. Discussions of tools and resources that contribute to effective teaching and learning include: services linking digital libraries with resources that can help educators teach more effectively (Cathy Manduca, Carleton College); identification of excellent digital resources through community review systems (Kim Kastens, Columbia University); inquiry and visualization-based curricula (Rajul Pandya, DLESE Program Center); the DLESE Evaluation Toolkit project (Susan Buhr, University of Colorado); the use of Dynamic Digital Maps (DDMs) to engage students in petrology by bringing the field into the classroom (Christopher Condit, University of Massachusetts); and the provision of geospatial search services by the Alexandria Digital Library (David Valentine, UCSB). Other presentations include the application of Earth system vocabularies for resource characterization that illuminate the interrelatedness and contextualized nature of thematic collections (Dave Mogk, Montana State University); the development of collection-level metadata for cross-data center searching (Greg Janee, UCSB); special collections formation such as the Digital Water Education Library (DWEL) (Bryan Aivazian; Natrona School District) and the Marine Realms Information Bank (Fausto Marincioni of USGS), as well as digitization of existing geological collections (Ian Hodgden, Perkins Geological Museum).

Online Education on the Rise
September 2002-- Students use the Web to complete their degrees, even as they move to other locations. By taking advantage of online educational opportunities, those who wish to pursue advanced degrees are no longer constrained geographically. Options for remote learning via the Web are so popular that even with the economy in a downturn and many degree-granting Internet sites closing, online education is still growing.--Flash Points, Col. 7, No. 5, Aug. 2, 2002.

E-books Get Mixed Response
September 2002-- Don't throw away your bookbags just yet. Although e-book pioneers say that cumbersome textbooks are a prime candidates to be replaced by e-books, a recent study shows that the technology still has a way to go. The study, conducted at Ball State University's Center for Information and Communication Sciences, compared the effectiveness of e-books versus textbooks, measuring both the learning experience, as determined by comparative test scores, and the usability of e-books. And while the good news is that learning was not negatively affected, the technology was still cumbersome. Students tested both black and white and color biology e-books, but without pictures, tables, or diagrams. Out of 91 subjects, 40 used the conventional textbook, 24 used the black and white e-book, and 27 used the color e-book. Quiz results were almost identical, with scores averaging 29, 28.9, and 28.5 respectively. However, students complained about e-books, ranging from a too-complex online manual to difficulty in finding a chapter, previously read material, or appendix. Book marking, word lookup, and search functions were not considered useful or easy to use. Also, they mentioned that glare and cold temperature affected performance. Further, the amount of time taken to perform certain tasks negatively affected the perception of the usability of e- books. Students also expected the features to have the same functionality as similar devices in computer programs or personal digital assistants and were disappointed with their limitations. The study made a series of recommendations to improve the usability of e-books, including a redesign of the menu, the ability to page up or down by more than one page at a time, and an increase in the screen size to 6" x 8.5" (from 5" x 7"). The study was funded with a grant from the Eli Lilly Foundation, with equipment donated by Thomson Multimedia.
