Three campus libraries offer collections with breadth and depth to support the curriculum and a variety of learning styles, and to encourage reading for enjoyment and discovery. Librarians provide instruction and support to help students use information and ideas effectively and creatively.

Cooke Library serves the Academy (grades 9-12), Bishop Learning Center serves grades 5-8 and Ing Learning Center serves grades K-4.

Students and teachers also have access to many magazine and newspaper databases as well as electronic reference books through the ePunahou portal. Once students login to their ePunahou account, they can click on the My Classes tab and then the link to Research Databases.
