According to Henry Spencer Ashbee, Reddie was a serious, exacting collector and bibliographer of erotica. When he acquired a new book he would immediately collate it, investigate every available authority on it, and compare the book page by page and word by word with any other issue of the same work. If he was unable to acquire a scarce book, he frequently made copies by hand. He never refused to lend a book from his vast collection, even though often the borrower would forget to return it. Reddie was always liberal with his knowledge of erotica, imparting information gave him great satisfaction, and he spared neither time and labor in his research.
