A Doujinshi (同人誌) is a Japanese work that a person creates alone or with people who also share their interests. A group of people who work together to create doujinshi are called a circle (サークル sākuru). Some circles have only one artist working by themselves: they are sometimes called kojin circles (個人サークル, personal circles). These works can be books, manga, art, or other things. Doujinshi are often created by amateurs, but, some professional artists also make doujinshi. The word "doujinshi" comes from doujin (同人, doujin, literally "same person" but meaning "people with the same interests") and shi (誌, ,"magazine"). Shi is a contraction of the full word zasshi. Zasshi means magazine.
Doujinshi are part of a larger category of dōjin. This category includes art collections, anime, hentai, and games.
