Doujinshi is fan manga. It's very hard to find most of the time since (as I understand it) only so many copies are produced. Of course, it's even harder to find them in America and they cost bookoodles of money ;_; but the artwork (depending on the circle) is GORGEOUS!!!
I've found that the best place to find doujinshi is eBay, however, if you're not old enough or just don't wanna bid for it, there are some online stores that sell a great variety of doujinshi.
If you're interested in doujinshi and don't know the first thing about them or don't know where to find them, please feel free to ask me!
