分析综合性全文数据库中限制期问题

The Questions of Embargoes Analysis on Full Text Databases

全文数据库中全文期刊数量不断增加的同时,带有限制期的期刊也将会大量出现,这一现象的存在,对于出版商而言是为了保护传统的印刷版和电子版期刊订购,对于图书馆来说会产生这样的误解:限制期的存在是否会减少数据库全文内容。因此,消除误解有利于图书馆利用限制使图书馆各类型资源一体化,而不是单纯提供在限制期刊与当前的索引数据库中进行无缝检索。全文数据库存在期刊限制信息远远胜过无全文信息的数据库。

The number of journals with embargo periods in aggregated databases designed for libraries has increased for the simple reason that the number of available full text journals in these collections has also increased. Misconceptions surrounding embargo periods deduce that embargoes diminish access to information by withholding the current full text from journals, embargoes increase access to information for journals that otherwise would not be available in aggregated databases. Embargoes exist for the purpose of preserving a publisher＇s traditional print and electronic journal subscriptions. The use of embargoes may be valid in one electronic resource, but not t he other. Linking capabilities provide seamless access from embargoed journals with current indexing in databases to the corresponding current full text found in a library＇s e-journal collection.
