It's like Christmas in July. Or in September, I guess.
This is wonderful news. Gollancz is one of the great and foolish imprints, like NYRB Classics, which I adore. They bring the greatest books of times past to us in lovely editions (sci-fi/fantasy for Gollancz, and literature/strangeness for NYRB). And now to have all the science fiction authors that I read as a youth, most of them drifting into the mists of obscurity and generally out of print, coming back in ebook editions, is terribly exciting.
