Baker Library Special Collections and Archives maintains numerous tools to assist users with locating books, serials, archival and manuscript collections, and other materials in our holdings. Please contact Special Collections reference staff for more information on using items you discover or to ask for assistance if you are unable to locate materials of interest to your research topic.


Special Collections and Archives materials are cataloged and searchable through various catalogs and databases (HUID/PIN login may be required to view certain materials). Information on our collections is available here.

HOLLIS Catalog

The HOLLIS catalog searches most library resources in a single unified system, including books, articles, media and more. Once you start typing a word in the search box, you can limit to "Library Catalog" and Location "Baker Business." Search results can be further refined by date, material type (book, archives/manuscript), etc. Select "Online" from the Show Only dropdown in the right-hand navigation to return results for material available digitally (some content may be accessible to current Harvard students, faculty, and staff only).

HOLLIS for Archival Discovery

Manuscript and archival collections have a finding aid, or collection inventory, that provides more detailed information about the organization and contents of a collection. Collections vary in size from one volume to hundreds of boxes and finding aids helps users narrow down the portions of the collection that are relevant to their project.

A majority, but not all, of our collections have online finding aids and are searchable in HOLLIS for Archival Discovery (though all collections open and available for research are cataloged in HOLLIS). You can search for specific Baker Library Special Collections and Archives finding aids here or browse all of our finding aids available in the system here.
