HOLLIS has two main parts. There’s the traditional Library Catalog of Harvard's books, journals, films, sound recordings, maps, and so on. Then there’s a huge additional database of articles, reviews, etc. which come from various sources outside Harvard. Many of these are available online through Harvard's subscriptions.

You can search the Library Catalog separately, or  -- especially if you want to see articles -- search for "Catalog and Articles" at once. These choices appear as soon as you start to type a search.
