This section is intended to give just a brief overview of the U.S. editions of the books that have been issued, but it is by no means the authoritative word on collecting. The focus is on the original series with emphasis on the more common editions that people may encounter. If you have additional information that you would like to see posted or would like to contribute some information, please e-mail me using the link at the left.
For much more detailed information on the collecting aspects of the Three Investigators series, be sure to vist my friend Seth's page at http://www.threeinvestigatorsbooks.homestead.com. He has a wealth of information posted there on all the books and as a BONUS, he has posted two interviews with William Arden (Dennis Lynds) and Gayle Lynds (G.H. Stone).
