Scholarly Communication and the Use of Networked Information Sources

This paper examines the use of networked information sources in scholarly communication. Such use is reflected, among others, in the footnotes and bibliographies of scholarly articles published in print journals. Twenty-seven print journals representing a wide range of subjects were identified through the ISI's SCI and SSCI Journal Citation Reports. Journals that were selected were those that published the most influential papers in their respective fields during the period of 1990-1993, and thus consistently ranked at the top in terms of their impact factors. From these top journals, a total of 97 articles were selected for further review. Footnotes and bibliographies of those 97 articles were checked to determine if they contained references to networked information sources such as electronic journals and archives accessible through the network. Only two (out of 97) articles contained such references. Findings were discussed in light of other studies published in the relevant literature. Some explanations were also offered as to why references to networked information sources appear relatively infrequently in scholarly articles published in print journals

Collection Development of Electronic Information Resources in Turkish University Libraries

The number of information sources available through both printed and electronic media are ever increasing. Even libraries with sizable collection development budgets are having difficulties in coping with this increase. Yet with the development of new technologies, the possibilities of innovative interlibrary cooperation projects emerge: libraries combining their efforts through various consortia are trying to get access to electronic information sources more economically. In this paper, we briefly review the state-of-the-art of Turkish university libraries and summarize the efforts to set up a university library consortium to provide consortial access to electronic information sources and services. We discuss some of the causes which are delaying the establishment of such a consortium

Libraries and Museums in the Flat World: Are They Becoming Virtual Destinations?

In his recent book, “TheWorld is Flat”, Thomas L. Friedman reviews the impact of networks on globalization. The emergence of the Internet, web browsers, computer applications talking to each other through the Internet, and the open source software, among others, made the world flatter and created an opportunity for individuals to collaborate and compete globally. Friedman predicts that “connecting all the knowledge centers on the planet together into a single global network…could usher in an amazing era of prosperity and innovation”. Networking also is changing the ways by which libraries and museums provide access to information sources and services. In the flat world, libraries and museums are no longer a physical “place” only: they are becoming “virtual destinations”. This paper discusses the implications of this transformation for the digitization and preservation of, and access to, cultural heritage resources

Inverse Nodal Problem for a Conformable Fractional Diffusion Operator

In this paper, a diffusion operator including conformable fractional derivatives of order {\alpha} ({\alpha} in (0,1)) is considered. The asymptotics of the eigenvalues, eigenfunctions and nodal points of the operator are obtained. Furthermore, an effective procedure for solving the inverse nodal problem is given

Interlending Services in Turkish University Libraries

The article begins with an overview of the current situation in Turkish university libraries, which were badly affected by the economic crisis of 1977-82. In 1982 the Higher Education Council (HEC) approved the centralization of university libraries, and HECDOC (HEC Documentation and International Literature Search Centre) was set up in order to develop a national collection of serials in support of university library collections. Up to now, interlending in Turkish university libraries has been largely neglected, not helped by a law which makes librarians personally responsible for all losses from their library. A survey of 28 university libraries has shown that current use of ILL services is not great, with the various libraries disagreeing in their attitudes to charging for ILL. HECDOC provides 55% of satisfied ILL requests and it is hoped that the creation of a union catalogue of serials, together with a standard photocopy request form, will increase this. Collection development in Turkish university libraries is seriously affected by declining budgets, rising literature costs and a shortage of hard currency. Resource sharing, including ILL, is seen as one way of solving these problems

Contribution of Turkish Researchers to the World’s Biomedical Literature (1988-1997)

The contribution of Turkish researchers to positive sciences is increasing. Turkish scientists published more than 5.100 articles in 1998 in scientific journals indexed by the Institute for Scientific Information’s Science Citation Index, which elevated Turkey to the 25th place in the world rankings in terms of total contribution to science. In this paper, we report the preliminary findings of the bibliometric characteristics (authors and affiliations, medical journals and their impact factors, among others) of a total of 8.842 articles published between 1988 and 1997 by scientists affiliated with Turkish institutions and indexed in MEDLINE, a well-known biomedical bibliographic database

Another proof of Pell identities by using the determinant of tridiagonal matrix

In this paper, another proof of Pell identities is presented by using the determinant of tridiagonal matrices. It is calculated via the Laplace expansion
