HOLLIS vs. HOLLIS Classic: Which One to Choose?

Both catalogs search Harvard's library collections, but what are the advantages of each?

HOLLIS has an easy to use, intuitive interface, built-in spelling correction, and relevance-ranked results. Refine search results with one click by author, date, language, or subject. HOLLIS includes more searchable tables of contents.

HOLLIS Classic is best for browsing alphabetical lists of names, subjects, titles, and call numbers. HOLLIS Classic supports searches using non-Latin characters and a powerful "expanded search" feature offers unmatched precision.
