Results of several research studies indicate that corporate reference collections may differ in kind and in definition from reference collections of other types of libraries. It was found that a corporate reference collection may not embody a "core"; it might not imply ownership of items; it might rely heavily on referral sources; and it might be redefined functionally as a wlndow or gate to rentable information. The corporate librarian may make little distinction between a reference book and any other item in the library collection. Further, evaluation of such a corporate reference collection entails the evaluation of other parts of the library. This includes the ability of librarians to use any source to answer reference questions or provide information for the decision makers in the corporation; such a mode implies that the presence of a reference collection may be counterproductive to the provision of information services. Methods of evaluation were also considered as indicators of performance distinct from output measures. 相似文献

This study focuses on the visual collections in the holdings of the Slavonic Library (a section of the National Library of the Czech Republic). The library holdings also include unique collections relevant to the topic of Russian and Ukrainian emigration: collections of visual art, ex libris, posters and flyers by Ukrainian émigrés (1918–1945), and a collection of invitations and flyers by Russian émigrés (1918–1945). Rudolf H?lka’s collection of photographs, dating back to the 1920s, captures a series of ethnographic, folkloric, and architectonic phenomena which no longer exist. Moreover, Russian posters from the period of WWI, from the revolutionary year of 1917, and the subsequent civil war are equally fascinating as are banknotes from the same period and region. 相似文献

On Collection Size and Retrieval Effectiveness 总被引：3，自引：0，他引：3
The relationship between collection size and retrieval effectiveness is particularly important in the context of Web search. We investigate it first analytically and then experimentally, using samples and subsets of test collections. Different retrieval systems vary in how the score assigned to an individual document in a sample collection relates to the score it receives in the full collection; we identify four cases.We apply signal detection (SD) theory to retrieval from samples, taking into account the four cases and using a variety of shapes for relevant and irrelevant distributions. We note that the SD model subsumes several earlier hypotheses about the causes of the decreased precision in samples. We also discuss other models which contribute to an understanding of the phenomenon, particularly relating to the effects of discreteness. Different models provide complementary insights.Extensive use is made of test data, some from official submissions to the TREC-6 VLC track and some new, to illustrate the effects and test hypotheses. We empirically confirm predictions, based on SD theory, that P@n should decline when moving to a sample collection and that average precision and R-precision should remain constant. SD theory suggests the use of recall-fallout plots as operating characteristic (OC) curves. We plot OC curves of this type for a real retrieval system and query set and show that curves for sample collections are similar but not identical to the curve for the full collection. 相似文献

After reviewing the historical significance of competitive rowing at Harvard and Yale universities and the literature dealing with rowing as a competitive sport, this article describes and reports the results of a checklist evaluation and simulated semi-availability study of the rowing collections of the Harvard and Yale University library systems. The results indicate, contrary to what might be expected, that major academic libraries can have noteworthy holdings in a specialized sports area. Harvard has a stronger rowing collection with a higher overall availability rate than does Yale. Comparison with a previous evaluation of the Free Library of Philadelphia's (FLP) rowing collection, based on the identical checklist, indicated its holdings are a bit stronger than Harvard's and considerably better than Yale's, but not as strong as the combined holdings of both Harvard and Yale. 相似文献

弘扬文化传统彰显个性特色-试论近年来高校图书馆特藏的发展 总被引：2，自引：1，他引：2
一流大学不仅要国际化和标准化,而且要特色化和个性化。特藏是体现图书馆及所在高校文化传统和特色的重要指标。文章通过分析和论述境内外四所具有代表性的大学图书馆的特藏建设,较为全面地观察和总结了近年来特藏发展的方向和流变:许多图书馆或创建内容丰富、形式活跃的“新特藏”,以凸现本校本馆特色,支持重点学科发展;或致力于发掘传统的“老特藏”,以梳理馆藏流变,彰显人文内涵和历史传统,传统意义上以“善本”为核心的特藏概念被扩大了。特藏建设已经成为图书馆揭示和打造其文化传统的一个重要方面。 相似文献

This article describes a method for using LibGuides as a tool for collection development by benchmarking peer (Carnegie or other classification) institutions’ reference resource recommendations. The results of this benchmarking can be used to build strong, compact collections. Although the focuses of this study are on building and maintaining of a sociology reference collection, the method transfers directly to other subject areas. 相似文献

One way to promote the relevancy of an academic law library is to create a special collection that generates interest in the patron base; a popular collection is a viable way of reinventing a law library's image in the hearts and minds of the law school community. Popular collections have been championed by general academic librarians because they promote reading and literacy, the use of the library as a place, and such collections represent the shift toward a user focused library model. Using data collected from interviews and analysis of collection development policies this article presents models of popular collections currently in use at academic law libraries, as well as considerations for the creation of such collections. 相似文献

The author presents strategies any librarian or researcher with access to OCLC WorldCat may use to answer many kinds of questions concerning foreign-language materials in their own or other libraries. These advanced searching strategies, some not obvious and some even hidden in the WorldCat interface, may also be used to help collection managers generate valuable information about their library’s collection strengths in specific languages, and by extension, make comparisons with collections at other institutions. Special attention is devoted to certain problems associated with Slavic and Eastern European languages. 相似文献

ABSTRACTAfter several centuries of intensive collection development activity, the major research library collections of North America and Western Europe, taken as a whole, can be expected to provide reasonable coverage for all of the world’s languages and peoples. One might also expect that any two languages with a similar number of speakers and a similar publishing output might have similar profiles in terms of the amount and quality of materials available to scholars in Western library collections. For the Turkic peoples of the North Caucasus (Kumyks, Karachais, Balkars, Nogais, and a few others), however, this is not the case. This article (which is Part II of a three-part series) demonstrates that, despite the scholarly value, intrinsic interest, and potential geopolitical significance of publications in North Caucasus Turkic languages, these publications are severely under-represented in Western libraries and, relatedly, in Western scholarship about religion, politics, history, culture, war and revolution on the northern perimeter of the Muslim world. Print and online bibliographic resources for the study of the Turkic peoples of the North Caucasus are considered, and are used selectively to assess the strength of Western library collections. Part I of this article appeared in the previous issue of Slavic & East European Information Resources (vol. 18, nos. 3–4). 相似文献

采用光沉积-液相化学法调节电子流向,构建了直接Z型TiO2/Ag/Ag3PO(4 )(TAAPO)光催化材料.通过扫描电子显微镜(SEM)、透射电子显微镜(TEM)、X射线衍射仪(XRD)、X射线光电子能谱(XPS)、紫外-可见漫反射光谱仪以及光致发光(PL)光谱仪等手段对其进行表征,并对其在可见光照射下催化降解环丙沙星(CIP)的性能进行了研究.结果表明,当水体pH为3.0,催化剂分散浓度为0.3 g/L,CIP的初始浓度为15 mg/L时,光催化降解体系能够取得最佳的去除效果.在该组条件下,光照120 min CIP的降解率约为99%,并且在经历4个循环后仍然保持了良好的降解效果.在光催化降解CIP的过程中,主要反应活性物种为超氧自由基(·O2 相似文献

The major serials collections in Australia have been seriously affected by adverse economic trends and changing collection development policies. The university libraries now have a crucial role to play in preserving and improving the quality of Australia's serials resources. In the midst of major changes to higher education encouraging competition among universities and emphasizing specific national priorities in research, the university libraries must promote a national perspective on serials collections, if Australia's resources are not to deteriorate further. 相似文献
