In the course of researching the life and work of a 19th century British artist, Henry Courtney Selous, several London museums and libraries were visited during 1993. The Royal Academy and the National Portrait Gallery yielded some information, but at the Guildhall Library the author’s attention was drawn to a diary held at the National Art Library which on perusal seemed undoubtedly to have been compiled by Selous. The Library has subsequently revised the diary’s catalogue entry to incorporate this attribution.
