二八定律与长尾理论在信息资源建设与服务的应用

The Application of Pareto Principle and Long Tail Theory in Library Collection Building and Library Service

二八定律与长尾理论是共生应用、双赢互补并互促发展的关系,并已被应用到信息资源建设与服务领域:在信息资源建设领域,可同时兼顾利用率高与利用率低的信息资源建设,以同时满足主体用户与尾部用户的信息需求;在信息资源服务方面,既能满足处于曲线头部的核心用户对信息资源服务的需求,也能够满足处于曲线尾部的用户长尾对信息资源服务的需求。

Pareto Principle and Long Tail Theory are the relationship of mutual application,complementary win- win and mutual development. They have been applied to the field of library collection building and library service. In the aspect of library collection building,they can take into account high usage and low usage library collection,as well as can meet the information needs of main users and tailor users. In library services,they can meet the needs of either core users in the curve head or tail users in the curve tail.
