There are several ways of getting hold of books not in the Library:

Morebooks: just send an email to morebooks@st-andrews.ac.uk detailing the book(s) that you are looking for. We will get back to you in 48 hours letting you know if we can purchase it or not.

Inter-Library Loans: we can order a book through inter-library loans for you. 

Dundee: University of Dundee (including the Robertson Trust Medical Library at Ninewells) and Dundee Abertay have reciprocal lending rights with St Andrews, so you can borrow books from them (although not electronic items). 

SCONUL Access lets you borrow from a number of Libraries throughout the UK
