WINSTON BOOK SERVICE, 250 Fulton Avenue; Hempstead, New York. Successor to the famous Cory Book Service which was founded by Donald Webster Cory, author of “The Homosexual in America”. This is perhaps the best American source for current novels in hard covers and non-fiction. They issue catalogs and lists, give a sizable discount for large orders, and will also locate hard-to-find or out-of-print books. Leslie Laird Winston, who is the presiding genius here, is one of the nicest people to deal with that we have ever known. Every month they feature some new or special book in the field, at a special price. Getting on their mailing list is the _best_ thing that can happen to a collector.
