Ronald DeWaal is the author of several extensive Holmes/Doyle bibliographies. The latest, 'The Universal Sherlock Holmes' is a massive four volumes that covers just about anything that ever had to do with Sherlock. From the original Strand to the novels to pastiches to radio, TV, movies to you name it. It's in there! If you want a copy and can not locate one, send me a note and I will send you the publishers address/information. I got my copy from 'The Sleuth of Baker Street' bookstore in Toronto.
