At one point Dream Corridor's original run was to go past issue 5. Dream Corridor #6 was solicited, but then cancelled and reformatted into Harlan Ellison's Dream Corridor Quarterly #1. According to Rabbit Hole 18 (The Newsletter of the Harlan Ellison Recording Collection) a format change was made. "Harlan Ellison’s Dream Corridor from Dark Horse comics is a big success. If you’re looking for issues past #5 then I’m afraid you’ll have to wait until next year. Dark Horse wanted to expand the market to the bookstores, so HE and his co-editor Anina Bennett are revamping the format. Square-bound, ‘perfect bound’ format [like the Special] to be published quarterly; at 64 pages per issue. It means a larger market, a bigger audience, serious attention."
