Cancelled charge slips collected over a one-year period supply the data for this analysis of circulation in the Yale Medical Library. Full-time teaching faculty are the heaviest users of journal literature, and students, of monograph literature. Faculties of Medical School departments are compared in terms of their use of material in individual subjects. Subject literatures are analyzed in terms of groups of users borrowing from them. The extent to which journal titles used by medical students are also used by Medical School faculty is examined. One of the products of the study is a rank list of journal titles used in the Library. Results are presented in several tables.  相似文献

Our paper analyzes the conduct of German public performing arts institutions in terms of non-market decision making or public choice. Apart from consumers of performing arts managers of performing arts institutions and public donors are main agents. A manager of a performing arts institution will not assume that the number of visitors is independent of his institution's programme or the ticket prices. By the same reasoning he will regard the amount of public subsidies not as exogenous, but dependent on his own policy. If future grants depend on present and past success (however defined), this will feed back into managerial decisions, along with expectations about demand. Data for the Federal Republic of Germany serve to empirically support the theoretical argument.  相似文献

Among the huge maze of resources available on the Internet, UnCoverWeb stands out as a valuable tool for medical libraries. This up-to-date, free-access, multidisciplinary database of periodical references is searched through an easy-to-learn graphical user interface that is a welcome improvement over the telnet version. This article reviews the basic and advanced search techniques for UnCoverWeb, as well as providing information on the document delivery functions and table of contents alerting service called Reveal. UnCover's currency is evaluated and compared with other current awareness resources. System deficiencies are discussed, with the conclusion that although UnCoverWeb lacks the sophisticated features of many commercial database search services, it is nonetheless a useful addition to the repertoire of information sources available in a library.  相似文献

This paper reviews the current situation in library school education for medical librarianship in the United States and Canada based on information from a questionnaire sent to teachers of courses in medical librarianship in accredited library schools. Since 1939, when the first course devoted entirely to medical librarianship was offered at Columbia University, courses have been introduced into the curricula of at least forty-seven of the ALA-accredited library schools. In 1978 there were seventy courses available through forty-seven library schools. Possibilities for specialization in medical librarianship are examined. Course content is reviewed. Implications of the MLA certification examination for library school courses are explored.  相似文献
