The new “glorious” paperback edition of Earth Abides will be released in mid-October. It can be pre-ordered now through your local, friendly, independent bookseller via BOOKSHOP or via Amazon.
This new printing is from Mariner Books (A division of Houghton Mifflin). It has, I think, the best cover for the book since the cover on the first edition in 1949:

It also includes an Introduction by distinguished author Kim Stanley Robinson. He offers a brief but focused biography of Stewart; then describes the novel in terms of its place in similar literature and in Stewart’s fine body of work. He also makes the obvious and timely comparison between the events of Stewart’s novel and the current pandemic – a reminder that this is the best of times to read Stewart’s encouraging novel.
Even if you already own a copy, this edition is worth buying for Robinson’s excellent Introduction. Or to read or re-read Stewart’s fine novel, to see how the amazing thinker and writer George R. Stewart imagined our time, 71 years ago, and wrote a novel to help us deal with it.

I think I already own half a dozen copies including the audiobook version. I might buy this one anyway. Just because!
