About us

Welcome to Cosin’s Library, one of the earliest public libraries in the North East of England. Hidden in the heart of Durham, the library was founded in 1669 by Bishop John Cosin to give local people access to ‘good books’. After a period of conservation work, we have now reopened the library to visitors. Whether you are interested in this important part of Durham history or in old books, you can either visit us in person or explore Cosin’s Library virtually.
