HOLLIS+, a new discovery system with intuitive interface, search precision enhances access to multiple types of materials from one starting point.


August 14, 2014—The Harvard Library launched its new HOLLIS+ service today, a new discovery system that enhances access to multiple types of library materials from one starting point.


  • Searches with precision across Harvard’s vast  library resources from a single starting point
  • Coherently aggregates Harvard materials along with licensed material, including non-textual media and grey literature
  • Integrates special collections materials
  • Supports interdisciplinary research
  • Links to Harvard’s resource delivery and fulfillment systems (Scan & Deliver, Borrow Direct, ILL, etc.)

Additional features of HOLLIS+ include:

Books and articles together. HOLLIS+ allows users to search for books and articles using a single search box.

Seamless user experience. HOLLIS+ allows users to remain in a single system for research and My Account functionality, such as saving results, viewing holdings, making requests, viewing account, renewing items. 

Chinese, Japanese, Korean and more. HOLLIS+ provides complete support for search and display of vernacular scripts and transliterations. It supports translation between simplified and traditional Chinese, and properly handles transliterations for non-Western languages such as Arabic, Hebrew and Cyrillic.

Exposure of special collections. HOLLIS+ supports ingestion of a wide array of data schemas. The system will allow Harvard to optimize functionality and display for image records and finding aids as well as other new types of metadata in response to future needs.

Browse searching. HOLLIS+ offers left-anchored browsing for author, title, subject and LC call number. 

Phrase searching/search precision. HOLLIS+ supports strong search precision for local content thanks to advanced indexing capabilities. It has the ability to handle known-item searching, single-word titles, phrase searching and advanced search options.

Search engine exposure. HOLLIS+ exposes data to web crawlers for inclusion in search engines such as Google.

Flexibility. HOLLIS+ provides extensive configuration options and an open framework to allow for Harvard development and responsiveness to user feedback.
