Baker Library Special Collections maintains numerous tools to assist researchers 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 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

HOLLIS+ includes everything from the Harvard collection and an enormous articles database. Search results can be refined, including limiting to Baker Business materials.

For tips on using this catalog, see the HOLLIS+ Help page.

OASIS (Online Archival Search Information System)

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

About twenty percent of our collections have online finding aids and are searchable in OASIS (though all collections open and available for research are cataloged in HOLLIS). You can browse Baker Library Special Collections finding aids in OASIS here by choosing "Baker Library, Harvard Business School" under Limit by Repository and clicking the Go button. 

For more tips on using the OASIS database, see the OASIS User Guide.   

Finding aids not yet available through OASIS can be sent electronically to researchers upon request.


Special Collections holds a rich collection of photographs, prints, engravings, trade cards and other images. A growing number (but not all) of these visual images have been digitized for online searching through HOLLIS Images, Harvard Library's dedicated image catalog (A HU PIN is required to view some full size images).

Search results can be refined by Date, Subject, and Form/Genre.
