A paperback edition of Prime Obsession was brought out in May 2004 by Plume, a division of Penguin Books, U.S.A. (New York). Other editions and translations followed. Below are shown the ones I possess.
Others certainly exist. I know, for example, that there is a Greek translation of Prime Obsession, and I know who did it (this guy). I have no copy, though, nor any idea how to get one. Sometimes the publishers of an edition or translation send me a copy; sometimes they don't. It's random. The ones shown here are just the ones I happened to get.
I have a dozen or so copies of each of the translations, so if you'd like one please email me at the e-address on my home page.
There is an essay about the Russian translation here.
