ABSTRACT

The article examines the most important periodicals of ethnic minorities in Poland. After 1989, many ethnic groups (e.g., Germans and Romanies) were allowed to publish journals and newspapers for the first time since the end of World War II. The publications examined show the rich cultural life of the various ethnic groups as well as their current status in Poland. In addition to popular titles, some scholarly publications are also discussed.  相似文献

The author answers a reference question on bibliographic sources for the Ukrainian periodical press 1840–1850. Helpful publications include bibliographies, guides, and library catalogs. These potentially make mention of revolutionary developments in Hungary (such as the Twelve Points paragraph of the Demands of the Hungarian Nation in March 1848, the subsequent April Laws, and Hungary's declaration of independence in April 1949), and elsewhere in the Hapsburg Empire.  相似文献

Most studies of collection development mask inadequate theoretical underpinnings with facile assumptions and dazzling statistical manipulations. This essay, in moving toward a model for collection development within both specific collections and library systems as a whole, seeks to demonstrate the full range and complexity of relevant factors. An enlarged theoretical grasp should help highlight both the possibilities and the challenges of existing approaches. One result could be a shift toward gaming or simulation techniques as more realistic analytical tools.  相似文献

An annotated list is presented describing seventeen periodicals that cover significant aspects of the gay, lesbian, bisexual, and transgender (GLBT) community and their culture in whole or in part, with popular content rather than an academic or research focus. The titles included are a selective and representative sampling. The entry for each periodical includes the following information: periodical title, publisher/editor and address, basic information, publication data, content, Internet information, an abstract/annotation, and evaluative statement  相似文献

SUMMARY

Ariel files are the starting point for electronic delivery of interlibrary loan articles through ILLiad, Virginia Tech's interlibrary loan system. Despite some advantages to electronic delivery of articles to their desktops, a large majority of ILL customers continue to prefer print on paper delivery rather than electronic delivery. This fact has implications for introducing additional electronic services. Correctly choosing what services to impose on library customers, and what services to offer as value-added options, is fundamental to maintaining the credibility of libraries during these times of rapid change.  相似文献

SUMMARY

The state of Illinois funded a large scale Ariel project. This is a report of the project's successes and shortcomings. Although widely successful, additional training in the use of sophisticated hardware, primarily Minolta scanners, is needed. Data on sending and receiving is included.  相似文献

SUMMARY

The authors discuss the development of the Slovak periodical press within its historical context and their expectations for its future. The article covers general characteristics of Slovak magazines and newspapers from World War II to 1989, and their later development since the Velvet Revolution up to the present. It also discusses the Slovak press outside of Slovakia from the late nineteenth century.  相似文献

Library Journal's 2011 Ebook Penetration and Use in U.S. Libraries Survey testifies to e-books’ increasing popularity in academic libraries. This review tracked literature published from 2005 that focused on academic librarians’ best practices for acquiring, cataloging, maintaining, and promoting e-books at their institutions. Some of these practices include implementing trial accesses, considering institutional requirements, providing an e-book presence in the library catalog, monitoring usage statistics, and utilizing the library Web site for promotional efforts.  相似文献

SUMMARY

There are between fifteen and twenty U.S. libraries that collect publications from Central Asia, defined here as Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan and Uzbekistan. Collection development responsibility for these countries tends to rest with the Slavic selector, the Middle East selector, or both, divided by language. Vendors who can supply this material mostly also supply publications from other countries of the former Soviet Union. The author briefly discusses the history of collecting from this region and the results of a survey conducted in 2004. She presents evidence indicating that the main reason U.S. libraries are not receiving more books from the region is most likely because they are not being published, not because vendors are doing an inadequate job.  相似文献
