As individuals become more and more comfortable mediating all kinds of situations online and through various technologies, their virtual selves increasingly overlap their "real" lives. Posting a "happy birthday!" message on Facebook is as automatic as dropping a card in the mail. E-mailing relevant links to co-workers happens as naturally as…

As information professionals attempt to meet the needs of scholars, a significant issue is the degree of correspondence between research tools created by library and information science professionals and research tools created and used by scholars in any particular academic discipline. Humanities scholars assign importance to the use of personal…

Researchers for small businesses, which may have no access to expensive databases or market research reports, must often rely on information found on the Internet, which can be difficult to find. Although current conventional Internet search engines are now able to index over on billion documents, there are many more documents existing in…

For the last three decades, the engineering higher education and professional environments have been completely transformed by the "electronic/digital information revolution" that has included the introduction of personal computer, the development of email and world wide web, and broadband Internet connections at home. Herein the writer compares…

This paper examines inclusive design delivery through interface design, with a particular focus on access to healthcare resources for seniors. The goal of the project was to examine how seniors are able to access drug information using two different online systems. In the existing retrieval system, pills are identified using a standard search…

This paper describes experiences in gathering together metadata from heterogeneous sources for the American Memory project of the Library of Congress, particularly for the collections digitized and cataloged at other institutions. It also reflects on several initiatives to develop rich structured metadata schemes for specific domains and to find…

Discusses the amount of time necessary to access, read, and annotate articles in bound journals and on 35-mm microfilm. Journal articles require an average time of 5.12 minutes to retrieve and read from bound volumes versus 6.17 minutes from microfilm. Abstracts from "Dissertation Abstracts" require an average of 1.9 minutes from bound volumes…

This discussion of the nature of classification schemes and their functions focuses on the differing classification systems of North American and European-type libraries. The functions are bibliothecal, bibliographical, and cognitive. The bibliothecal function concerns the physical location of items within a library (e.g., the Dewey Decimal and…

Discusses two query evaluation strategies used in large text retrieval systems: (1) term-at-a-time; and (2) document-at-a-time. Describes optimization techniques that can reduce query evaluation costs. Presents simulation results that compare the performance of these optimization techniques when applied to natural language query evaluation. (JMV)

Discusses ways to improve and standardize intellectual access to electronically published historical documents. Highlights include metadata; information retrieval; the need for user studies; the need to assess implications for change in publication management; and the need to compare empirically various technological approaches to access to…

Presents a broad view of information access, drawing from philosophy and semiology in constructing a framework for comparative discussion that is used to examine the information representations that underlie four approaches to information access--information retrieval, workflow, collaborative filtering, and the path model. Contains 32 references.…

Describes the nature of intellectual access to digitized art images using qualitative methodologies based on a study at the University of Central Florida. Queries of art historians are analyzed and compared to retrieval parameters and image characteristics, and implications for database design are suggested. (Author/LRW)

Discusses results of a survey of music technical services librarians that investigated retrieval problems with the symbols for sharp and flat in music notation in online catalogs. Comparisons are made with an earlier study of online catalog vendors, and a list of institutions surveyed and the questionnaire used are appended. (LRW)

Describes characteristics of subject gateways on the Web (i.e., facilities allowing easier access to network-based resources in a defined subject area) and compares them to search engines (e.g., AltaVista). The application of WHOIS++, centroids, query routing, and forward knowledge to searching several gateways simultaneously is outlined, and…

Character strings were planted in a World Wide Web site (Project Whistlestop) to test indexing and retrieval rates of five Web search tools (Lycos, infoseek, AltaVista, Yahoo, Excite). It was found that search tools indexed few of the planted character strings, none indexed the META descriptor tag, and only Excite indexed into the 3rd-4th site…
