HOLLIS Catalog
holliscatalog.harvard.edu

The HOLLIS (Harvard On-line Library Information System) Catalog, which is open to the public, contains over 10 million records for all types of material in the Harvard University Library system. It serves as the primary access point to books, journals, manuscripts (more detailed descriptions of manuscripts are provided through OASIS), government documents, maps, microforms, and music scores.

Using a HUID and PIN, members of the Harvard community are able to use HOLLIS to renew, hold, or recall items; to view a list of items checked out; and to check fines on-line.
