Abstract

Journal article overlap is defined as the same journal article being indexed by two or more services. Using journal references from seventy dissertations written in the preclinical sciences, the extent of journal article overlap among Index Medicus, Science Citation Index, Biological Abstracts, and Chemical Abstracts was examined. Of the 7,969 journal references cited, 92% were indexed by at least two of these services; 591 articles were covered by only one of the services, and 55 articles were not indexed. A discussion of the advantages and costs of journal article overlap is presented.

摘要

期刊文章重叠被定义为同一篇期刊文章被两个或更多服务机构索引。利用70篇临床前科学领域的博士论文中的期刊参考文献，研究了《医学索引》《科学引文索引》《生物学文摘》和《化学文摘》之间期刊文章重叠的程度。在引用的7969条期刊参考文献中，92%被这些服务机构中的至少两个索引；591篇文章仅被其中一个服务机构涵盖，55篇文章未被索引。本文还讨论了期刊文章重叠的优点和成本。
