HOLLIS is the library's main search interface. It includes the Harvard library catalog as well as a huge (and more heterogeneous) collection of citations for a variety of materials, including articles and book chapters.
This User Guide describes HOLLIS's system features. If you would like search advice specific to your topic, please Ask A Librarian.
Do this first. Why? Because you need to be signed in to:
Note: alums must access online resources via the links on library.harvard.edu's page for alums. Alums can still use their HOLLIS accounts to manage requests, save favorites, and personalize results, but HOLLIS's "view online" links will only work if the item is publicly accessible, as is the case with Harvard-digitized or HathiTrust items.
To view items you have checked out as well current requests, saved items, and other details, use the drop-down menu that appears next to your name once you have signed in.
*Items on Harvard’s shelves includes books, journals, newspapers, maps, DVDs, manuscripts, images, archives, and much more. The Library Catalog also searches the full text of Harvard’s archival finding aids, as well as the tables of contents for some books (i.e. individual chapter titles).
Note: the Catalog’s descriptions are maintained by Harvard staff and follow well-established rules for author names, subjects, and other descriptive components. This is why you'll find more reliable filters when you limit your search to Library Catalog.
**"Everything" is NOT actually everything. It searches the Library Catalog as well as a huge index of citations. This index of citations pulls information from a wide variety of data sources. The descriptions are not under the control of Harvard staff, and they follow a huge variety of conventions for description and naming.
Even if Harvard doesn’t currently own an item, we can usually get a copy for you. “How to Get It” will take you through the steps.
