Dōjinshi are made by artists or writers who prefer to publish their own materials. Avid fans of dōjinshi attend regular dōjinshi conventions, the largest of which is called Comiket (short for "Comic Market") held in the summer and winter in Tokyo's Big Sight. At the Convention, over of dōjinshi are bought, sold, and traded by attendees. Dōjinshi creators who based their materials on other creators' works normally publish in small numbers to maintain a low profile from litigation. This makes a talented creator's or circle's dōjinshi a coveted commodity as only the fast or the lucky will be able to get them before they sell out.
