Also available for download courtesy of Suvudu are some classic titles.
The Stealer of Souls (1963) by Michael Moorcock
With a forward by Alan Moore, this volume contains not only the original story collection of the title, but also one of Moorcock's early Sojan stories, letters, and even Stormbringer, the penultimate title of the entire Elric saga.
I forgot to mention that there's a post over on the Tachyon blog in which The Readers of Boing Boing interview Michael Moorcock. Well worth a read if you're a fan.
Red Mars (1992) by Kim Stanley Robinson
The first volume in Robinson's Mars trilogy, which became an instant classic.
For Love of Mother-Not (1983) by Alan Dean Foster
The first novel in Foster's Pip and Flinx series, telling the timeless story of a boy and his minidrag. There's also an interview with Alan Dean Foster over at BSC. The interviewer strikes a frivolous tone and is overly effusivive, giving the whole thing a rather insincere feel, but it's still a good intoduction to Foster and his works.
