Zoology is a diverse subject, ranging from cell biology to ecology and this is represented in the Library. There are also specialized collections on the major groups of animals, especially birds and insects. Books on undergraduate reading lists are purchased for all Part I and Part II courses taught by Zoology. Many of these have copies for both overnight and longer loan and some are also available as e-books. There is a rare book collection consisting of over 8,700 volumes which date from the fifteenth to the mid-twentieth centuries.
