Where are the History Books Located?

Most history books have Dewey Decimal call numbers between 900 and 999. In Ryan Library, these books are primarily shelved on the second floor, West wing. However, some books are shelved in special collections, such as the Irish Collection. The library catalog will indicate when a book is not shelved in the main collection, and many books will have a letter before the call number. To see all of Iona's library locations, consult the complete list of Iona's library locations and collections.
