  • Keyword searches are a great way to start
  • It’s always a good idea to physically browse a subject area and look at the books
  • The majority of the library books are in the general collection, but we have many special collections (Cardinal Newman Collection, Reference, Juvenile, Thesis, Videos and more)
  • Special collections are shelved separately from the general collection
