This article has been written by Harpreet K. Dhillon, with contributions from colleagues at Gray's Inn Library, Inner Temple Library, Middle Temple Library and Lincoln's Inn's Library. During the course of the article, Harpreet looks at the way the four of Inns of Court libraries support barristers, though will use the term members interchangeably throughout. The Inns have their own histories, and the libraries function in their own unique ways, so the focus of this article are those key services provided by all the libraries and their relevance to the continuing work of Inn members. The article has been written using anecdotal evidence and contributions from all the library teams, concluding that the Inn libraries play a crucial and ongoing role in supporting the work of barristers, a role that evolves and will continue to do so alongside the legal profession's demands.
