基于Z39.50的联机书目检索服务

Online Bibliographic Retrieval Service Based on Z39. 50

联机书目检索服务是在网络环境下图书馆应当向读者提供的重要服务．基于Telnet或者Web的联机书目检索服务存在检索接口不一致的问题，而239．50协议为这种问题提供了解决办法．文章描述了一个基于Z39．50的联机书目检索服务系统．该系统支持中文检索和包括CNMARC在内的多种MARC（machine－readablecataloguing）类型，具有灵活的可配置性和可伸缩性．文章还给出了系统的主要技术设计，并与已有的相关系统进行了简单的比较．

The online bibliographic retrieval service (OBRS) is a main service which should be provided by libraries on network environment. Every OBRS provided via Telnet or Web has its own access procedures and a special user interface and query language. The Z39. 50 protocol offers a solution to heterogeneity problem. In this paper, a system that provides OBRS based on Z39. 50 is described. The system supports Chinese retrieval and multi-MARC (machine-readable cataloguing ) including CNMARC, and is highly configurable and scaleable. Main technical design and simple comparison with related systems are given in this paper.
