John Lorne Campbell was one of the foremost scholars of the Gaelic world. His library on Canna is possibly the finest collection of Gaelic material in existence and has now become a study centre. He was the author and editor of many books and was responsible for putting into print some of the major figures of the Gaelic world, such as The Coddy, from Barra and Angus Maclellan, from South Uist. His wife, Margaret Fay Shaw, still lives in Canna House. Canna was first published in paperback by Canongate in 1994.
