Doujinshi creators who base their materials on other creators' works normally publish in small numbers to maintain a low profile so as to protect themselves against litigation, making a talented creator's or circle's doujinshi a coveted commodity. At the convention, over 20 acres (81,000 m 2) of doujinshi are bought, sold, and traded by attendees.
Since the 1980s, the main method of distribution has been through regular doujinshi conventions, the largest of which is called Comiket (short for 'Comic Market') held in the summer and winter in Tokyo's Big Sight. Several such groups actually consist of a single artist: they are sometimes called kojin sākuru ( 個人サークル, personal circles). Groups of doujinshi artists refer to themselves as a sākuru ( サークル, circle).
Part of a wider category of doujin (self-published) works, doujinshi are often derivative of existing works and created by amateurs, though some professional artists participate in order to publish material outside the regular industry. Doujinshi ( 同人誌), also romanized as dōjinshi, is the Japanese term for self-published print works, such as magazines, manga, and novels.
