Carty, a British secondhand book dealer, has expanded the second edition of this work to include nearly 17,000 pseudonyms of more than 10,500 authors. (The first edition, published in 1995, included 12,000 pseudonyms for 7500 authors.) Following a brief "Select Bibliography," the dictionary is divided into two parts. 

Part 1 lists pseudonyms (both proper names and attributions such as "A Russian Lady") and initialisms in alphabetical order with references to the real name or names. Nicknames or diminutive forms of names are also included, such as Peter Marcus Adlard's pseudonym, Mark Adlard. 

Part 2 lists real names with vital dates, nationality, a brief description of the person, pseudonyms used, and representative titles in which pseudonyms are used. Pseudonyms used in journals and newspapers as well as names used in books are noted. The text does not indicate whether the writer uses his or her given name in addition to a pseudonym or whether one pseudonym predominates. Writers from the early 17th century to the present day are included, but the emphasis is decidedly British and historical. 

Although this book is not as authoritative as Contemporary Authors or as browsable as Adrian Room's Dictionary of Pseudonyms (LJ 10/1/98. 3d ed.), which often describes the origins of the pseudonyms of people in many other fields as well as writers, it is an easy-to-use one-volume resource.
