The series is divided in two groups: three actual books titled "The World" that were released in 1990, and two catalogues titled "Exhibition" released in 1993 and 1995 respectively. They contain many color illustrations of Dr. Slump, Dragon Ball, and Dragon Quest, as well as a few of Toriyama's one-shots and exclusive interviews with Akira Toriyama. The numerous illustrations featured in the five books are reused several times from one book to another, as well as in the Dragon Ball art and data books.
