J. Michael Straczynski told Facebook readers August 12th that The Last Dangerous Visions has been finished.
THE LAST DANGEROUS VISIONS has at last been completed. The final draft went off to the agency that will be handling the sale about fifteen minutes ago. This has been a massive effort…112,000 words…tracking down the estates of the original writers to be included in the book, and nailing down some newer A List writers; fans of Harlan’s who wanted to be a part of TLDV. (And for the record, Harlan continued to buy stories for the anthology right through the 90s, and stopped only due to illness. He saw TLDV as a living document, and fought to keep it relevant when some stories became less timely or were supplanted by real world events.)
I will have more to say about the contents at a later date, but suffice to say that they include some of the most visionary writers in the science fiction genre over the last 48 years.
