All correspondence is from Ronald Johnson to Moore unless otherwise indicated. The letters are in chronological order except for the folder of Ian Hamilton Finlay correspondence, which is at the end of this series. Consists of typed letters (often with handwritten emendations, corrections, and signatures), postcards, and greeting cards. Johnson rarely addressed his letters to Moore consistently, frequently using nicknames and playful variations on Moore's name.

Items sent with letters, including drafts of verse, remain with the correspondence in this series.
