Ellison published Dangerous Visions, a seminal collection of short, groundbreaking SF stories from a mixture of the genre's biggest names and hottest newcomers, in 1967. It was rapturously received, selling a huge number of copies. Ellison followed it up with Again, Dangerous Visions in 1972. The Last Dangerous Visions was announced shortly thereafter, originally with a mooted 1973 publishing date. The book expanded, becoming more ambitious, and by 1979 Ellison was talking about publishing it in three volumes. Ellison claimed to be working on the project through the 1980s and 1990s, but at a certain point it became his white whale. Early memes about how the book would never come out proved popular, and author Christopher Priest even wrote a nonfiction book about the situation called The Book on the Edge of Forever.
Ellison's passing in 2018 would have seemed to have made the situation moot, but Ellison had asked his friend J. Michael Straczynski to work on bringing the project to fruition. That process has now been completed, with Blackstone Publishers picking up the rights to The Last Dangerous Visions as well as reprint rights for its two predecessors. They will issue the books as 2023 in individual volumes and a unified edition.
A full table of contents is forthcoming, although it is known that Cory Doctorow, Neil Gaiman and James S.A. Corey (aka Daniel Abraham and Ty Franck) have contributed stories. Other authors include Edward Bryant, Stephen Robinette, Max Brooks, DM Rowles, Dan Simmons, Cecil Castelluci, Stephen Dedman, Patton Oswalt, Jonathan Fast, Howard Fast, Robert Sheckley, and Adrian Tchaikovsky (and yes, the overwhelming maleness of the list has been noted, although the list is not exhaustive). The book will include a mixture of brand-new stories from contemporary authors like the above and some of the stories slated by Ellison for the book in the 1970s, as well as one story by Ellison that has not appeared before. The book will also incorporate artwork by Tim Kirk.
It will, of course, be impossible for any book to live up to fifty-one years of expectations, but it should be an interesting volume.
