ABC University Library in 1962. The core of the collection now contains 10,000 volumes. There are works for advanced study and research, rare books and manuscripts, and a reading collection for undergraduates. Beyond this core are scores of books in departmental and special libraries, the most notable being those of law, business, sciences, engineering and technology, Chinese and Japanese languages and culture.

The library functions include borrowing of books, returning of books (with or without penalties) and reserving books. The selection, ordering and payment for the books is outside the scope of this investigation. On receipt of the new book the librarian has to make out a book card for insertion in the book sleeve and the relevant entries for the indexes.
