What are the functions of academic library?

Academic libraries have the same function as any other type of library - to collect, store, and provide information to the subscribing public. The special part of an academic library is its focus, which is narrowed to the area of academic interest the library is associated with. For instance, a veterinary medical library will have primarily books and journals related to veterinary medicine; you won't find Nora Roberts' latest fiction book in this library, nor even most human medical journals.
