ABSTRACT

As technology continues to influence the way we do business, change has been and will continue to be inevitable. All around us, we see the Internet playing a major role in our lives from the way we pay bills and do banking to the way we buy stock, shop as consumers, and obtain an education. You can't escape it, and librarians long ago realized this truth. To wit library services have evolved to accommodate the informational needs demanded by this ever-expanding industry. This evolution of library services can be seen, for example, in the way we promote and provide reference, circulation, and reserves services with inroads even into technical or resource services. With distance education libraries are positioning themselves to be major players in this phenomenon at all levels: local, national, and international. One library service that is beginning to proceed into the distance-learning arena is interlibrary loan/document delivery. Interlibrary Loan, a traditional library service for local users, whether provided by an academic, public, or special library is finding itself in the distance education movement. To explore this, the focus of this article is to examine the ways in which interlibrary loan impacts and supports distance education through technology and services.

UCMP and the Internet help hospital libraries share resources.

The Medical Library Center of New York (MLCNY), a medical library consortium founded in 1959, has specialized in supporting resource sharing and fostering technological advances. In 1961, MLCNY developed and continues to maintain the Union Catalog of Medical Periodicals (UCMP), a resource tool including detailed data about the collections of more than 720 medical library participants. UCMP was one of the first library tools to capitalize on the benefits of computer technology and, from the beginning, invited hospital libraries to play a substantial role in its development. UCMP, beginning with products in print and later in microfiche, helped to create a new resource sharing environment. Today, UCMP continues to capitalize on new technology by providing access via the Internet and an Oracle-based search system providing subscribers with the benefits of: a database that contains serial holdings information on an issue specific level, a database that can be updated in real time, a system that provides multi-type searching and allows users to define how the results will be sorted, and an ordering function that can more precisely target libraries that have a specific issue of a medical journal. Current development of a Web-based system will ensure that UCMP continues to provide cost effective and efficient resource sharing in future years.     

U.S. Public Library Outlet Internet Connectivity: Progress Issues and Strategies

The 1998 Public Library Outlet Internet Connectivity study (Bertot & McClure, 1998) sponsored by the American Library Association (ALA) and the National Commission on Libraries and Information Science (NCLIS) collected public library outlet Internet connectivity data by outlet metropolitan status, poverty, and region strata. Based on a national survey, the results show that there are disparities in public library outlet Internet connectivity, public access provision, and speed of public access Internet services. Such disparities have implications for future connectivity policy development such as the e-rate, state library-based connectivity programs, and library-initiated connectivity initiatives that this article identifies and explores. Community Access Points (CAPS), in addition to public libraries, may be necessary to reach national goals related to universal service and equality of access to the Internet.     

Placing the Internet in information source horizons. A study of information seeking by Internet users in the context of self-development

The ways in which people perceive the relative value of the Internet when seeking information for self-development purposes were investigated. The concept of information source horizon was introduced, and it is a construct that enables one to put various information sources and channels in an order of preference to meet the requirements of information seeking. The horizon is based on one's conceptions of the characteristics of information sources, particularly their accessibility and quality. The study draws on interviews with eighteen Internet users who positioned various information sources in three zones of relevance. In their information source horizons, human sources such as friends and colleagues were preferred, followed by print media such as newspapers and books: networked sources were ranked third among six source types. Networked sources were favored for easy accessibility and opportunities to save time. The issue of “facilitating everyday life” was emphasized in this context. Also currency, broad repertoire of networked information, and the potential of the Internet to complement other services were valued highly. Critical stands on the Internet were mainly affected by the negative experiences of encountering low quality material.     

United States v. Carmichael: Prior Restraint and the Internet

The discipline of communication is marked by an increasing number of means of understanding. Given the recent research explosion, specialization has accordingly become a major way of dealing with research and methodological diversity. Within this context, this analysis is predominantly definitional, seeking to isolate the unique features of qualitative research. This analysis first provides a survey of six major definitions of and approaches to qualitative research. Second, commonly shared characteristics of qualitative research are outlined, including the role that natural setting plays in the research design, the role of the researcher as both observer and participant, how subjects influence the content of a communication study, the influence of subject intentionality on the research report, and the pragmatic uses of qualitative research. Third, it is suggested that qualitative research is theoretically unique, satisfying the requirements for grounded theory. Finally, it is concluded that qualitative research is increasingly finding its own identity when viewed in terms of the goals and procedures of quantitative and critical approaches to communication.
