Getting Started

HOLLIS is a great place to start your research. 

HOLLIS is the library's main search interface. It defaults to searching billions of citations for articles, book chapters, and other materials (“Catalog & Articles”), along with the millions of items in the Harvard Library Catalog. Learn more about the differences between Catalog & Articles and Library Catalog.

Citation in HOLLIS 

Harvard does not own everything in HOLLIS. “Check Access Options” will bring you to a request form, or staff at Ask a Librarian can help you locate a copy. Learn more about access options.

No citation in HOLLIS

HOLLIS is huge, but it’s not everything. Fill out a blank Interlibrary Loan form and we will try to get a copy for you. You can also suggest we buy a copy for our collection

HOLLIS may have a citation for the journal but not the individual articles, the book but not the individual chapters, the box of archival materials but not its contents, or no citation for the item at all.

Alums and Guests


Use the links on's page for alums for alumni access to online resources. HOLLIS's "online access" links will only work for you if the item is publicly accessible, such as Harvard digital collections, HathiTrust items, or Open Access journal articles. 

Sign in to your HOLLIS account to manage requests, save favorites, and personalize results. 

Note: My Favorites carries over when you become an alum - any items saved to your HOLLIS account will still be there.
