Ask a librarian at HLS (or your place of employment or a local law library) to help you find a treatise.
Browse the stacks
Once you have an idea of the call number for your subject, you can browse shelves in that area for books that might be helpful. Keep in mind that not everything we have is on the shelf: items may be checked out by others, some treatises are now only available online, and some of our print collection is housed offsite at the Harvard Depository and is only findable through HOLLIS. Most treatises at the Depository are no longer updated.
Explore subject headings
To find more titles in the HOLLIS catalogue, click through to an individual title in this guide, then click the relevant subject heading links for more books on that subject.
HOLLIS is the catalogue of materials owned by Harvard in both print and electronic formats. Use the HOLLIS tab to find books. Do a keyword or subject search, then use the facets to limit your search to the HLS Library. Note: Most treatises don't include the word treatise in their titles, so it tends not to be a useful search term.
