If the Library doesn't hold what 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 Library has many dictionaries, encyclopaedias and biographies, including language dictionaries, subject dictionaries and specialist encyclopaedias. Below are some examples of what's online.
To connect to library resources such as databases and journals you will need to use the University’s VPN service called Globalprotect. Advice on how to set your connection up can be found on the iSolutions page How do I set up VPN on my device?
