Don't buy a 1st edtion Tarnsman with an ISBN!
When searching for an overview of the Gor-series, there are hundreds of websites available, each with more of less acurate information about the books in question. Some websites only list the first 25 books of the series, from Tarnsman of Gor to Magicians of Gor, a clear indication that they haven't been updated since August, 2002, when Witness of Gor was published; others, usually the most reliable, even mention Smugglers of Gor. Usually, one might suspect, this information is copied from one website to another, for example, when a new Gor book is published, but nobody bothers to check the information thoroughly, and when errors are made, they rapidly spread over the entire world wide web.
Currently, on the Internet, the First Printing of the Ballantine Edition of Tarnsman of Gor is usually identified by ISBN 0-345-02385-0 or 0-345-27583-7, while the First Printing of Outlaw of Gor has ISBN 0-345-02486-9 or 0-345-27136-X. Examples are "Books by ISBN" (books-by-isbn.com), "Fantastic Fiction" (www.fantasticfiction.co.uk) and even the Wikipedia pages for Gor and John Norman (en.wikipedia.org).
They are all wrong!
In a brand new, detailed analysis entitled "Breaking the Code... The Ballantine Enigma", The Complete John Norman reveals new ISBNs for the Second Printings of Tarnsman of Gor, Outlaw of Gor and Priest-Kings of Gor, and the First Printing of Nomads of Gor, and shows that Ballantine implemented the SBN numbering system after the publication of Priest-Kings of Gor in December, 1968. The First Printings of Tarnsman of Gor, Outlaw of Gor and Priest-Kings of Gor might simply not have an ISBN, but if they do, it is somewhere in the range between 0-345-00001-0 and 0-345-01764-1. The three books themselves do not contain an ISBN.
If you want to buy a first edition Tarnsman of Gor on the Internet, look for "Ballantine Fantasy Adventure U6071", and if the seller mentions an ISBN, walk away!
