Hellblazer has been incompletely collected into many trade paperbacks. The first UK editions, printed by Titan Books, reprinted the original colour issues in black and white. Though subsequent editions were in colour, they were not numbered and not always released chronologically. While some issues were never collected in trade form, some early issues appear in books. As of June 2014, some issues remain uncollected. They are 107–128, and 229.
