What's in the HOLLIS Catalog

HOLLIS is the library catalog for Harvard University. It contains records for millions of books, journals, manuscripts, government documents, maps, microforms, music scores, sound recordings, visual materials, data files, and more. The catalog is updated continually as material is ordered, received, and processed. Two search interfaces are available, HOLLIS and HOLLIS Classic.

There are several important differences between HOLLIS and HOLLIS Classic:

Scope: The traditional collections of books, journals, manuscripts, etc. are covered in both HOLLIS and HOLLIS Classic. HOLLIS additionally searches a wider array of materials including finding aids for archives and special collections, images from visual collections, and enhanced tables of contents.

Search/Browse: Use HOLLIS for keyword searching with relevance-ranked results and refinable result lists. Use HOLLIS Classic for browsing lists of authors, titles, subjects, or for searching/browsing call numbers.

Non-Latin scripts: To search using non-Latin scripts (e.g. Chinese, Japanese, etc.), use HOLLIS Classic. Both HOLLIS and HOLLIS Classic display non-Latin scripts.

Neither HOLLIS or HOLLIS Classic currently supports article level searches. To locate articles, or narrow your focus to e-resources and e-journals, consult E-Research at Harvard Libraries.

Best Browsers to use with HOLLIS

The best browsers to use with HOLLIS and HOLLIS Classic are Mozilla Firefox 3.0 and above and Safari 4.0 and above. Other browsers will work, but may cause unexpected behavior.

Popup Blocking

The catalog uses popups in certain places. Some browsers can be configured to block popups, so be sure to allow popups when using the catalog. Check the help document of your browser for more information. In addition to browsers, some other software, such as the Google Toolbar and Norton Internet Security, have popup blocking functions. Check the help document of the software to find out how to allow popups.

Other Catalogs at Harvard

Other online catalogs at Harvard include VIA (Visual Information Access), OASIS (Online Archival Search Information System), and the Harvard Geospatial Library. Much of this content is also available in HOLLIS. To conduct a thorough search for materials, consult with librarians by starting with the Ask a Librarian service.
