Scholarly journals have served he academic community well for almost 350 years. They are thoroughly embedded in the process of scholarly communication. These journals have developed their own genres and formats, supporting scholarship in subtle ways. As we move into the electronic age, scholarly journals will evolve and change. The role of librarians and scholars in guiding and nurturing the evolution of these journals into new forms is examined.  相似文献

The NLM Gateway is a single Web interface for searching multiple NLM databases. While the majority of the available databases can be accessed directly via their own Web sites, such as PubMed, there are three databases that are unique to the NLM Gateway, including the ever-expanding OLDMEDLINE files. Thus, the Gateway is a necessary tool for librarians and researchers to be familiar with and have handy.  相似文献

[目的/意义] 利用期刊零被引率对国内图书情报学期刊的零被引现状进行定量分析,并探究论文零被引的一些原因。[方法/过程] 在参考前人研究成果的基础上,提出期刊零被引的计算方法,利用中国引文数据库和中文社会科学引文数据库的数据计算国内14种图书情报学期刊的零被引率。[结果/结论] 研究发现:①14种期刊的零被引率整体较低,反映出这些期刊上的论文大部分被研究人员所引用;②根据13种期刊零被引率分布状况,可以将其分为"锯齿型"、"W型"、"下滑型"3种类型。③论文零被引的主要原因是选题太偏和有些研究主题不属于图书情报学领域。虽然研究了国内部分图书情报学期刊零被引情况,但研究方法和一些研究结论对于其他学科期刊的零被引研究有一定借鉴意义,同时对期刊评价等方面的研究也有一定的参考价值。  相似文献

Summary

The World Wide Web makes it possible for patrons to link easily to electronic journals but does not resolve problems of selection, acquisition, serials control, and cataloging. A pilot project undertaken at the University of Southern California Libraries involved creating a subject and title index to e-journals of interest to the USC faculty on the Web with links to the journals. Upon completion of the pilot, maintenance of the collection was assigned to the Serials Department in the University Library. It then became necessary to mainstream e-journal collection maintenance into the technical services operations of the library.  相似文献

以2012年JCR收录的数学期刊为例,采用偏度、峰度、JB检验、极大极小值比、离散系数、中位数均值比分析期刊评价指标的数据分布特点,并首次采用基尼系数分析期刊评价指标的内部差距,发现期刊评价指标普遍是右偏的,并且不服从正态分布;总被引频次、特征因子、即年指标的内部差距较大。期刊评价指标数据偏倚情况从好到坏的次序为:影响因子与5年影响因子>被引半衰期>论文影响分值>即年指标>特征因子>总被引频次。得出结论:指标数据偏倚会影响评价指标的数据标准化;指标数据偏倚会影响期刊一般水平的判断;指标数据右偏会导致期刊评价值偏低;最好选取数据偏倚情况相对较好的指标来评价期刊平均水平;数据偏倚对基于传统回归的计量研究影响较大。该结论有待进一步检验。  相似文献

Summary

This paper describes die OCLC Online Computer Library Center, Inc.s electronic publishing program between its introduction in 1992 through the late summer of 1997, focusing on OCLC's ongoing efforts to integrate electronic journals with library acquisition, cataloging, archiving, and online reference systems. The paper begins by describing the OCLC Electronic Journals Online (EJO) service, emphasizing how that service evolved to meet the changing needs of institutional subscribers to electronic journals between 1992 and 1995. It then describes the Electronic Collections Online service, a Web-bascd service introduced in June of 1997 that provides access to, and archiving for, hundreds of journals from many publishers.  相似文献

Archival science and postmodernism: new formulations for old concepts   总被引:1,自引:1,他引:0  
Process rather than product, becoming rather than being, dynamicrather than static, context rather than text, reflecting time andplace rather than universal absolutes – these have become thepostmodern watchwords for analyzing and understanding science,society, organizations, and business activity, among others. Theyshould likewise become the watchwords for archival science in thenew century, and thus the foundation for a new conceptual paradigmfor the profession. Postmodernism is not the only reason for reformulatingthe main precepts of archival science. Significant changes in thepurpose of archives as institutions and the nature of records areother factors which, combined with postmodern insights, form thebasis of the new perception of archives as documents, institutions,and profession in society.This essay explores the nature of postmodernism and archival science,and suggest links between the two. It outlines two broad changes inarchival thinking that underpin the archival paradigm shift, beforesuggesting new formulations for most traditional archival concepts.  相似文献

Process rather than product, becoming rather than being, dynamic rather than static, context rather than text, reflecting time and place rather than universal absolutes—these have become the postmodern watchwords for analyzing and understanding science, society, organizations, and business activity, among others. They should likewise become the watchwords for archival science in the new century, and thus the foundation for a new conceptual paradigm for the profession. Postmodernism is not the only reason for reformulating the main precepts of archival science. Significant changes in the purpose of archives as institutions and the nature of records are other factors which, combined with postmodern insights, form the basis of the new perception of archives as documents, institutions, and profession in society. This essay explores the nature of postmodernism and archival science, and suggest links between the two. It outlines two broad changes in archival thinking that underpin the archival paradigm shift, before suggesting new formulations for most traditional archival concepts.  相似文献

The purpose of this study is to determine the comprehensiveness and composition of university library holdings of marketing journals for three types of university library holdings of marketing journals for three types of institutions: schools that offer a doctoral degree program in marketing; non-doctoral degree programs in marketing offered at schools accredited by the AACSB; and non-doctoral degree programs offered at non-AACSB accredited schools. The results offer useful information for university librarians and marketing educators responsible for making journal acquisition and discontinuation decisions.  相似文献
