Farah's Guide 12th Printing is now available. This 12th Printing has been more than five years in the making and celebrates its 20th year in print. It has been entirely revised and includes over 170 new listings and completely updated pricing information. It is the only reference that allows a collector to distinguish between a first printing and a later printing of the Nancy Drew Mystery Series and to determine the value of each book and dust jacket.

Farah's Guide, 12th Printing contains 556 pages listing 2745 printings published between 1930 and 1979. Each listing includes dust jacket and book prices, and describes dust jacket and book advertising, cover stock, endpapers, pre-text pages and post-text pages, printing errors and changes in art and text.

Besides information on the printings of the series, Farah's Guide, 12th Printing describes the history of the series and gives biographies of its authors and illustrators. It also contains more than 135 photos of the authors and illustrators, models used for the covers, Nancy Drew collectibles and the oddest items associated with the series. For example, the Guide includes a photo of the ledger page used by Mildred Benson to record her sale of the first Nancy Drew story, a copy of the contract between Benson and the Syndicate for volume #5, copies of letters between Harriet Adams and Mildred Benson, and between Walter Karig and Mildred Benson, and reproduces the earliest known published article mentioning the series (from 1931), among other great Drewobilia.
