Sequels
The popular collection was followed by an even larger 1972 sequel, Again, Dangerous Visions. The projected third collection, The Last Dangerous Visions, was started, but controversially remains unpublished. The final book has become something of a legend as science fiction's most famous unpublished book. It was originally announced for publication in 1973, but other work demanded Ellison's attention and the anthology has not seen print to date. He has come under criticism for his treatment of some writers who submitted their stories to him, whom some estimate to number nearly 150 (and many of whom have died in the ensuing almost four decades since the anthology was first announced). In 1993 Ellison threatened to sue New England Science Fiction Association (NESFA) for publishing "Himself in Anachron", a short story written by Cordwainer Smith and sold to Ellison for the book by his widow, but later reached an amicable settlement. British SF author Christopher Priest critiqued Ellison's editorial practices in a widely-disseminated article titled "The Book on the Edge of Forever". Priest documented a half-dozen instances in which Ellison promised TLDV would appear within a year of the statement, but did not fulfill those promises. Ellison has a record of fulfilling obligations in other instances, including to writers whose stories he solicited, and has expressed outrage at other editors who have displayed poor practices.
