从工作实践中,笔者发现机读目录的字段指示符不被编目人员重视,在录入机编数据时,容易忽视或漏掉,因而使书目数据库的字段指示符混乱,造成CNMARC格式与其他元数据格式不好转换。本文通过对字段指示符的分析,确定其在CNMARC格式中的重要性,同时指明其赋值情况 相似文献

中国机读目录(CNMARC)是信息技术发展和资源共享要求下的产物。它完备的标准是实现信息机构间数据转换和资源共享的必要条件。图书在版编目(CIP)数据核字号是国家新闻出版总署为编制好的在版编目数据赋予的唯一一个核准号码。CIP数据核字号可以作为一个信息标注点融入到CNMARC中,以区分和检索图书。 相似文献

计算机检索书目数据失败原因 总被引：3，自引：0，他引：3
在利用计算机检索书目数据时,经常会遇到这类情况,明明是数据库里存在的数据,而检索人员却检索不出来,出现检索失败的现象。出现此原因,主要是由于在建立书目数据库的过程中,录入人员在细节上处理不同而造成的。笔者根据长期工作积累,具体归纳如下:1 字母大小写不一致由于一些应用软件区分大、小写,不能规定大、小写字母的意义相同,因此在建库时,录入人员应与出版物一致,照实录入。而有些名词、述语,对于某一领域、某一专业的读者来说,已形成习惯性用法,因此在检索时,选用字母大、小写不同而造成漏检或检索失败。例:计算机专业人员通常用ｄ… 相似文献

Bibliographic management tools have been widely used by researchers to store, organize, and manage their references for research papers, theses, dissertations, journal articles, and other publications. There are a number of reference management tools available. In order for users to decide which tool is best for their needs, it is important to know each tool's strengths and weaknesses. This article compares four reference management tools, one of which is licensed by University of Medicine and Dentistry of New Jersey libraries and the other three are open source and freely available. They were chosen based on their functionality, ease of use, availability to library users, and popularity. These four tools are EndNote/EndNote Web, Zotero, Connotea, and Mendeley Desktop/Mendeley Web. Each tool is analyzed in terms of the following features: accessing, collecting, organizing, collaborating, and citing/formatting. A comparison table is included to summarize the key features of these tools. 相似文献

SUMMARY This introduction to Africana reference describes the populations of researchers, the kinds of questions they ask, and how librarians–both specialist and generalist–may respond. It explores issues in “known-item” searches, including name authority and access to material in collected works and series. Choices made by authors, publishers, indexers, librarians, and researchers themselves have an impact on topic searches. Terminology for African languages, ethnic groups, place names, and topics cause problems for novice researchers, but library policy decisions can also impede access. Errors of all kinds–minor or major–can block access to information. The speed of electronic desktop publishing seems to have encouraged reduced care with proofreading, indexing, and verification of quotations and citations. The need for accurate information about Africa is great, but the market for publications and electronic resources focused on Africa is relatively small. This low market share can result in less coverage of Africa in indexes and reference tools. Despite the difficulties encountered in researching Africa, researchers and the librarians who assist them benefit from the tools, services, and initiatives of specialist Africana librarians and from a number of commercially produced resources. 相似文献

This paper examines the effect of modifiers on the stability of a vinyl acetate/ethylene copolymer dispersion adhesive upon aging. Eighteen common modifiers were added to a well-characterized vinyl acetate/ethylene copolymer dispersion (Dur-O-Set® E-150) in known concentrations and dry-film samples were subjected to 16–17 years of dark aging and seven to eight years of light aging. Yellowing, pH, gloss, swelling, cohesive strength, and flexibility were monitored for changes upon aging. Generally, the neat Dur-O-Set® E-150 (no additives) was found to become acidic on aging, but was fairly resistant to yellowing. It also swelled substantially in toluene, was of high gloss, medium strength, and flexible, and remained so on aging. No modifier was found to improve these properties. Various solvents, wetting agents, and thickeners did not alter the properties by much, while plasticizers, freeze-thaw stabilizer, glycerin, and certain fillers had a more negative effect. 相似文献

ABSTRACT Advances in computing power have accelerated the growth of knowledge and created opportunities. However, the resulting tidal wave of information presents challenges, including vast quantity with varying quality. In higher education, curation offers one solution as librarians and faculty, as educators and researchers, increasingly curate knowledge for students, colleagues, and other stakeholders. Using integrative and systematic methods, the purpose of this literature review was to examine curation in education. This article presents major findings related to the panorama, perspective, people, product, place, purpose, and process of curation in education. We also discuss major themes including the changing and expanding landscape of curation from curating artifacts to content and data, from non-formal to formal learning contexts, from individual to collaborative curation, and the role of curation in education in bridging people, communities, and knowledge. 相似文献
