Nine letters and eleven poems from Iris Murdoch to William Wallace Robson, to whom she was briefly engaged in the 1940s. Many of the letters and poems are on their relationship.

Letters sent from Iris Murdoch to her friend and fellow author Brigid Brophy. Murdoch and Brophy met in 1954 and maintained a friendship from then until Brophy's death in 1995. The period of the mid-1950s to the end of the 1960s was a time when the two were particularly close, although the letters do show the passionate nature of the relationship as Brophy sometimes sent accusing or angry letters to Murdoch, and these letters show Murdoch responding in kind. The letters also cover Murdoch's work and travels, plus views on current events, music, literature and art.

The letters are split into 7 files- the first three are letters from Murdoch which Brophy had separated out into a filing cabinet, and the fourth are letters from Murdoch to Michael Levey with a selection of other items such as photographs. File 5 contains dated letters arranged in chronological order, File 6 previously undated letters, and File 7 postcards and lettercards.

Letters sent from Iris Murdoch to her friend and fellow philosopher Philippa Foot from 1942 to the 1990s.

There followed a period of some estrangement as Philippa Foot married historian Michael (MRD) Foot, following his previous relationship with and subsequent rejection by Iris Murdoch. Their friendship was rekindled in 1959 following Philippa Foot’s divorce, and they remained friends and corresponded regularly while the latter was based in the USA. In the letters their friendship is discussed, as well as their work in philosophy and literature, and events taking place in the wider world at large.
