| 摘 要： | 联合书目系统是图书馆联盟内资源共享的前提和基础,虚拟联合目录是联合书目发展的方向,但虚拟联合目录存在检索结果集合并与排序难度大、成员馆检索压力大等缺点。为此,本文提出了一个由OPAC、馆际服务器和联盟间服务器组成的层次式虚拟书目系统,能更好地处理检索结果集、减轻成员馆的检索压力,该系统易扩展,更适合图书馆联盟不断发展壮大和联盟间不断融合的发展趋势。

| Abstract: | Union catalog is the premise condition for sharing resources in library consortium, and is developing from physical union to virtual union catalog progressively. But it is still difficult to sort, merge and de-duplicate the result items in virtual union catalog. In this paper, a layered virtual union catalog is presented, which is comprised of OPAC Server, Inter-library Server and Inter-consortium Server, much more efficient to process the result items than current versions of virtual union catalog. |
