How can I access the data underlying HOLLIS records?

Is there a bulk download option or an API?

In an individual HOLLIS record, you can select View Source (MARC) to see an xml translation of the underlying MARC record. Note: the xml includes a number of additional cross-references and other enhancements not present in the MARC.


Our LibraryCloud API provides HOLLIS data in MODS or DublinCore format. For more information, see Harvard Library APIs & Datasets.


If you need more information, please submit a question to Ask a Librarian.


Have another HOLLIS question? Our HOLLIS User Guide provides an overview of HOLLIS's features and functions.
