HOLLIS User Guide

Use HOLLIS's library codes to find (almost) all items in a particular Harvard library's collection, without having to enter a search keyword.

The list below includes most of the library codes currently in use along with a selection of location codes for the most popular subcollections. Contact Ask a Librarian if you need the code for a collection or subcollection not listed here.

More information on how to search HOLLIS by Code: Library + Collection.

Pro Tip: The total counts displayed in HOLLIS’s filter menus are approximations and are not suitable for reporting purposes. For accurate numbers of total holdings in a particular library’s collection (e.g. number of journals held), you must use a dedicated reporting tool.
