Six artbooks have been released containing Touhou Project material. Each of these artbooks has a different theme; for example, Bohemian Archive in Japanese Red focuses on characters, while The Grimoire of Marisa is solely dedicated to different kinds of spell cards. It should be noted that Seasonal Dream Vision is semi-official; it is more of a compilation of comics from various authors, along with an original story written by ZUN himself.
