Where is the User Guide for HOLLIS Databases?

HOLLIS Databases doesn't have its own User Guide, but here are a few tips:


HOLLIS Databases searches descriptions (not the contents) of the major electronic resources licensed by Harvard Library. All of these descriptions can also be found in HOLLIS, but Databases provides a customized search experience for when you want to find specialized search engines and large collections of digital materials.


You can use the same search operators as HOLLIS. Just remember that you are searching a subset of HOLLIS records.


In addition to the Library of Congress subject headings that you find throughout HOLLIS, Harvard librarians assign custom subjects to our Databases (these are the subjects listed under “Best Databases for…”).

For each of our custom subjects, Harvard librarians’ top 3 recommendations will display at the top of the page, under “WE SUGGEST.” Additionally, our top 10 recommendations for each subject are starred as “Best Bets.”

Additional technical documentation is available on our staff wiki
