Hello...

 

Villanova University’s Falvey Memorial Library has harnessed the power of contemporary Web search technology to develop an open-source resource discovery portal – VUFIND – that enables users to query and browse the library’s resources in a simple yet sophisticated manner. VUFIND is a “next generation catalog” that empowers users by supporting personalization and social networking services such as tagging and peer-to-peer comment sharing

 

Interesting features are the facets to refine search results, the tagging system, the possibility to add reviews and notes to the records and cite them, the availability infos inside the record itself, the similar items and many more. You can check them out at the live demo of VuFind.
