HOLLIS+ vs. HOLLIS Classic

Both HOLLIS+ and HOLLIS Classic search Harvard's library collections, but what are the advantages of each?

HOLLIS+  is Harvard’s scholarly alternative to Google. You can find and access articles, books, and more in one search. It is an easy starting point for exploratory research. It is useful for interdisciplinary research because it draws on a wide range of resources, covering a broad range of subjects. Searching is simpler and more intuitive. It is great for finding known items and for keyword searches.

Make sure you have signed in with your HarvardKey because you will have access to the most content, including content available only to Harvard ID holders.

HOLLIS+, however, is new and cannot currently search all of the Harvard Library’s journal collection at the article level. For this reason, you may need to supplement your HOLLIS+ search by using the Religion Quick Search or subject-specific database, such as the ATLA Religion Database (both are easily available from the library’s home page).

See the HOLLIS+ Quick Tips research guide for search tips and for giving feedback.

HOLLIS Classic offers a powerful “expanded search” feature that offers unmatched precision. It does not search images, most tables of contents, manuscript finding aids, or articles.
