If you can't find the books you need, you could check the catalogues of other libraries.
It is possible to visit most other UK academic libraries by joining SCONUL Access. You should only visit the British Library if the resources you need are not accessible from any other Library.
The Hartley Library uses the Library of Congress classification scheme for most subjects. The books are arranged by codes called 'call numbers'. Here are some of the most important call numbers.
The H (social sciences) and J (political science) books are located on level 3 of the Hartley Library. Other useful books may be located in other sections. Relevant books may also be located in other University of Southampton site libraries, for example, some health books are held at the Health Services Library (General Hospital).
The Library has many dictionaries, encyclopaedias and biographies, including language dictionaries, subject dictionaries and specialist encyclopaedias. Some are in hardcopy and others online. Below are some examples of what's online.
