<正> 一、远程联机检索的发展现状远程联机检索自70年代末以来发展非常快,据不完全统计,1979年至1988年全世界的联机检索系统从59个增至576个,数据库从400个增至3803个。商业行情、产品信息、统计数据、厂商名录和理化性质等数值和事实型数据库数量猛增,全文数据库和图形检索已进入实用。情报媒体已向小型化和高密度化转化,预计1990年光盘将进入联机检索系统,数据库生产实现产业化,联机检索系统的创建实现国际化,如联邦德国、日本、美国三国合作,在  相似文献

西文MARC编目在著录规则和MARC格式上与中文Mare编目有较大不同,再加上语言障碍使得相当一部分图书馆的西文编目存在较大的困难,深圳朗图公司的ILASⅡ图书管理软件在全国各类图书馆拥有大量的用户,ILASⅡ软件功能强大,深受用户欢迎。但是ILASⅡ的联机编目模块存在较大的缺陷。一是ILASⅡ联机编目(ILASⅡ-239.50)模块与RASⅡ联机编目(Calls-239.50)模块不能通用,在很多高校图书馆用户使用CAMS帐号进行联机编目,在使用ILASⅡ时则只能使用ILASⅡ联机编目(CALLS-Z39.50)模块进行联机编目,但是此模块只允许单服务器单条件检索,因而不能充分利用多个联机编目数据源。ILASⅡ联机编目(ILASII一239.50)模块虽然支持多个服务器检索,但却不能检索CALLS的详细编目数据,并且此模块同样不能支持条件组合检索并常与服务器掉线,因此使用起来也极不方便。在中文编目时,由于CALLS的命中率极高,利用ILASⅡ联机编目(CALLS-239.50)模块基本上可以保证了较高的编目质量,但是在西文编目时,由于书籍的来源较为广泛,单一CALLS的命中率相对中文书低了许多,加上语言障碍和西文著录格式的复杂性,同时在因特网上又存在大量的西文联机编目资源,这使得使用ILASⅡ的用户迫切需要一个更加方便实用的联机编目客户端来辅助ILASⅡ进行西文联机编目,笔者在实践中发现丹诚公司的ZTRANS软件可以极大地弥补ILASⅡ联机编目的不足。  相似文献

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

ABSTRACT

The history of the almanac in Croatia is reconstructed through primary research in bibliographic and archival sources. The almanac is a vehicle for knowledge communication in informal contexts, engaging both oral tradition and literary forms traceable to medieval literacy and ways of structuring knowledge. The history of the almanac in Croatia reflects the changing context of the book trade, literacy, and the evolution of language. Four main stages are identified: (1) the beginning of the annual almanac in the seventeenth century; astrological almanacs reflecting the sensibility of the Baroque period; (2) the Enlightenment's stimulation of almanac publishing in the spirit of contemporary secular reforms in agriculture and education; (3) nineteenth-and twentieth-century almanac trade, showing complex and overlapping networks for the production, distribution and appropriation of printed almanacs;(4) roughly the end of World War II, when the almanac slowly moved out of the role of a popular mass medium and into specialized niches represented by regional, diaspora, and religious almanacs.  相似文献

ABSTRACT

German authorities are expecting more than 1 million refugees by the end of 2015. These people come to Germany to seek protection and assistance and to build a new life, therefore it is important to welcome them and to assist them in their integration as soon as possible. This situation creates a versatile and perfectly fitting opportunity for cultural and educational programs, including libraries, which can play a vital role in this integration process. The key to integration is the knowledge of the German language, and the most important challenge now is to teach the necessary language skills to as many asylum-seekers as possible.  相似文献

Abstract

Many libraries use RSS to syndicate information about their collections to users. A survey of 65 academic libraries revealed their most common use for RSS is to disseminate information about library holdings, such as lists of new acquisitions. Even though typical RSS feeds are ill suited to the task of carrying rich bibliographic metadata, great potential exists for developing applications that can exploit metadata exposed to Web services via RSS. Using the MODS metadata format, entire catalog records can be seamlessly embedded in RSS 2.0 feeds. Existing tools, such as Library of Congress Java toolkits and XSLT stylesheets, can facilitate this process, while a new XSLT stylesheet may be used to create the RSS feeds complete with MODS records. As an example of the added functionality these MODS/RSS feeds can offer, records from a MODS-enriched RSS feed can be ingested into a non-RSS application such as Zotero. As more emerging library technologies use Web services architectures to handle data objects, the ability to syndicate catalog records will become more critical to providing innovative library Web services.  相似文献

SUMMARY

The Nevada Constitution provides voters with the ability to propose new statutes, amendments to existing statutes, and amendments to the State constitution through the initiative petition process. Voters can also approve or disapprove of existing statutes through the referendum petition process. Both require the circulation of a petition to collect a minimum number of signatures before the Secretary of State will place the measures on the ballot for the general election. As with other topics of law, Nevada has a profound shortage of research resources on initiatives and referenda, but State law and government Web sites provide enough information to allow for significant research.  相似文献

SUMMARY

This article is a case study of Ariel use at the University of Texas at Austin. The author divides the history of Ariel use into three distinct stages: resistance, full implementation, and enhanced. For each stage the advantages and disadvantages of using Ariel are discussed. The author concludes that using Ariel saves both money and staff time and permits faster delivery of documents than other methods.  相似文献

SUMMARY

CISTI, the Canada Institute for Scientific and Technical Information, is one of the world's largest document delivery suppliers, and was among the first to be fully automated. The revolutionary Intel-liDoc system, developed during the years 1993 to 1995, provided for end-to-end automation of the document delivery process, which has enabled CISTI to improve its service and accommodate growth. From the beginning Ariel was, and remains, an integral part of IntelliDoc. This article describes how Ariel has been integrated into IntelliDoc and into CIS-TI's services, showing the benefits to CISTI and to its clients.  相似文献
