The series "In one volume" was created in 2005 to reprint popular cycles in it in one volume. A prerequisite was not just a collection in one volume, but also a mandatory afterword about the cycle as a whole. Sometimes a new illustration was created for reprinting, although more often a picture was put from one of the previously published volumes. A considerable volume of volumes (usually 800-1200 pages), an increased format and good white paper made the books of the series very popular. Most of the works were reprints from the Fantastic Action, Humorous Series and Fantasy Magic series, but there were also unique volumes that were not published anywhere else.
