From the Guardian:
... from Arthur C Clarke to Philip K Dick, Marion Zimmer Bradley to Robert Silverberg, Gollancz is making thousands of classic out-of-print SFF titles available as ebooks. The SF Gateway launches this autumn with more than 1,000 titles by almost 100 authors, with plans to increase this to 3,000 titles by the end of 2012 and 5,000 by 2014. Wow. "Wherever possible, the SF Gateway will offer the complete backlist of the authors included," says Gollancz in its announcement.
A complete list of the authors already signed up – they're negotiating with many more – is here (warning: PDF). Tanith Lee is there, and deservedly so – I wrote here about how I couldn't believe she was out of print. Harry Harrison, James P Blaylock, Theodore Sturgeon, EE "Doc" Smith, my beloved Tim Powers – it's basically the great and the good of science fiction and fantasy, and they're all going to be available at the click of a button (pricing is yet to be revealed, but will be "in line with prevailing market trend, but competitive and value for money", apparently).
Wonderful development, I think.
