(Yeah, I still haven't fixed the PC with Dreamweaver, Photoshop, and all the website-related files that died a few months back. But hey, I have an actual job again.)
Back in 2006, Christie's, the auction house, had a massive auction of Star Trek stuff, and commemorated it with a full colour catalogue of two trade paperbacks. This year Propworx held a major Trek auction and did a full colour catalogue in book form as well -- one volume, but hardcover instead of paperback. It's a very attractive coffee table book that could well appeal to the people who bought Star Trek 365 and the Haynes Enterprise Manual. But if you're not sure you want to buy it, Propworx is letting you have a pdf for free.
You can't beat a deal like that, but the book is worth having in print form anyway. Look at the downloadable version and think how nice a hardcover edition of it would be. And it's cheaper than the Christie's catalogue was, too...
