Heythrop Library

The Heythrop Library is a philosophy and theological library in London, England. The library was part of University of London when it functioned as the closed Heythrop College library. The library has continued to operate, independently of the closed college. Between 2018 and April 2025, the library was an affiliated library of the Senate House Library, which meant that it shared the library management system and database with the bigger library.

The library has been serving the Jesuit community in the United Kingdom, with The Telegraph calling it "one of the oldest and most important libraries of theological and philosophical books in the UK".

Since 2019, its reading room has been providing access to the collection at the London Jesuit Centre, Mount Street, Mayfair, London. The vast majority of the collection is housed in several off-site storage facilities. Only 8,000+ books and the latest issues of the 150+ live journals are available in the reading room. The library purchases in the region of 700 books on theology and philosophy each year.

The library is open to "anyone with a serious interest in theology or philosophy and the related academic disciplines represented in the collection", with different membership options available (from "free" to an annual charge). Current HE students, Jesuits and other Religious, as well as those unwaged might be able to benefit from free membership. The Library continues to provide historic as well as most-current research, in print, to those in training for ministry in the Catholic and other Christian churches and of the wider academic community. It also supports those engaged in programmes at the London Jesuit Centre.

The library is a member of ABTAPL (the Association of British Theological and Philosophical Libraries).
