[目的/意义]信息资源发现与传递服务一直是图书馆的核心业务，目前在欧美出现一种新形式即基于Bento模式的联邦检索服务系统，研究其最新发展趋势对完善我国图书馆发现系统有重要参考价值。[方法/过程]通过文献调查、比较研究、案例分析等方法，对比国内外发展现状，揭示混合排序的不足和Bento模式的优点，并以美国伊利诺大学香槟分校（UIUC）图书馆为例说明其应用和未来发展趋势。[结果/结论]实践证明Bento模式更有利于实现从全资源发现向全图书馆发现的转变，检索效果和图书资源利用率均有较大幅度的提升。
[Purpose/significance]The information resource discovery and delivery service has always been the core business of the library. Over the past 20 years, the collection and contents of academic libraries have changed. The resource discovery system has also evolved a lot under the impact of Google Scholar and other network platforms. From the super catalog and federated search in early stage to a more popular web-scale discovery service system at present, till now another new resource discovery system emerges which is called the hybrid Bento-style federated search service system.[Method/process] This article revealed the insufficiency of mixed sorting and the advantage of Bento display through comparing the development of discovery systems in academic libraries both at home and abroad. In the end, we illustrated the application and future trends of discovery systems by taking University of Illinois at Urbana-Champaign (UIUC) Library as an example.[Result/conclusion] It is proven that the Bento pattern helps libraries to reform itself from full-resource discovery to full-library discovery. The search results and the usage rate of library resources are increasingly enhanced.
