Frog God Games has posted three free downloads at the FGG site.
The first is the text of all the lair material from the Compiled Tome of Horrors. If you have the S&W version of the book, you already have this, but it's a good preview, if you don't have the book, of what you get in addition to the monsters descriptions.
The second is a listing of the Tome monsters by terrain. This is nice additional material even for those with the S&W Tome already.
Third is a teaser preview of the compiled Deskbook series, which now has the sexier title of "Ultimate Book of Adventure Design." Since it's not specific to a ruleset, the same printing is being sold to both the old school and the Pathfinder markets without a change in text or cover, which makes it less expensive to product (only one setup fee at the printer). I haven't downloaded this yet to see which tables were selected for it.
