The Mary Alice & Tom O’Malley Library supports the work of faculty and students through its collections, facilities, and services.  Reference librarians are available to help with students' academic work, and the librarians teach information literacy and advanced research classes to students in all subject areas.

The library is open 24 hours a day during the academic year.  The collection includes 450,000 books and more than 48,000 current journals, including all the journals of the most prominent scholarly publishers: Elsevier, Oxford University Press, SAGE, Springer Nature, Taylor & Francis, and Wiley. Through the Library website, students on or off campus can access more than 220 databases that provide access to journals, books, and reference materials.

Students and faculty of Manhattan College can also use libraries throughout New York City and Westchester County through the on-site arrangements established by WALDO, our local library network.  Books and articles from libraries worldwide are available through our interlibrary loan service.

O'Malley Library has four computer labs with more than 100 computer workstations as well as conference rooms and a wide range of areas for individual and group study.  An Internet Cafe is located outside the main library entrance.

The Library maintains the Manhattan College Archives as well as the De La Salle Christian Brothers Archives of the New York and Long Island-New England Districts, the District of Eastern North America, the Midwest District, the Christian Brothers Conference, and the Lasallian Research Collection.
