There are a whole bunch of computer related publishers, a few off the top of my head: O'Reilly: http://www.oreilly.com/oreilly/author/intro.html Sams: http://www.samspublishing.com/write.cfm Or just pick a book at random and get in touch with the publishers. Both of those sites have guidelines sections in them, but they would probably vary from publisher to publisher. -- Lindsay Evans.
