Now that David Louis Edelman's Geosynchron, the final book in the Jump 225 series, is out, we are getting emails from folks who can't find the first book in the trilogy, Infoquake, on Amazon. The reason for this: Amazon has just changed their search results in a baffling and frustrating manner. Now, under the stated purpose of offering "more choices" to consumers, they only display what they deem the "best edition" of a volume in a search string, rather than all editions. (The "best edition" seems to mean the most recent as far as we can tell.)
Thus, in the case of Edelman's Infoquake, the Solaris mmpb, being the most recent, is the only edition they will return in a search. The Pyr edition is still in there, but it's difficult to find. You have to click on "paperback" in the "formats" box, and then it will come up.
But just in case you are having trouble, here it is. And here is Multireal.
I hope that Amazon will restore the full capabilities of their search engine, since the resource that their database used to represent was one of their primary strengths. Meanwhile, I see that the Pyr edition of Infoquake pops right up on Barnes & Noble and Borders.
