A number of Cotman related sales and exhibitions catalogues collected by Kitson during the course of his Cotman research. Most of the books bear Kitson's name and some are annotated by him. There are some items in between pages, for example press and magazine cuttings, letters and invitations.
James Reeve was one of the first to recognise the importance of Cotman's watercolours and his efforts to establish John Sell Cotman as a major artist were endorsed by the British Museum who purchased a substantial part of his collection which Laurence Binyon assessed in 1897. Post-war interest in the artist was rekindled in a comprehensive exhibition of work by the Cotman family at the Tate Gallery in 1922 with a linked display in the British Museum Print Room.
