Iris Murdoch's library as held at her house in Oxford. The books were collected by Iris Murdoch throughout her lifetime. The books predominately relate to her interests in philosophy, theology and psychology, with some on other subjects including poetry and mysticism. Approximately half of the books were annotated by Iris Murdoch, some of them to great length and detail. The annotations show her thoughts on the books and on philosophy and theology in general. This went on to influence her philosophical teachings and writings, as well as inspiring themes in her novels. The majority of the books date from the 20th Century, however there is a few older texts within the collection, the oldest dating to 1535. The collection also contains some of Murdoch's notebooks, particularly her notes on the work of Jean-Paul Sartre and on songs she was taught during the 1930s.
With the books a collection of music scores and sheets was acquired, with some song books dating back to the late 1800s. Many of these were inherited by Iris Murdoch from her mother, Irene. There is also a collection of beer coasters collected by the author, and some terracotta oil lamps dating from the Roman period.
