Monthly Serial Novel Magazines?
DeeryQueen asks: "I enjoy reading both regular/text novels and Japanese graphic novels (manga), but while there are a few magazines serializing manga (a few hundred pages each month, consisting of a chapter each from many different graphic novels) with which I am familiar (such as Shonen Jump and Shojo Beat), I don't know where to start looking for US magazines which serialize text novels using this formula. I read all genres. Any recommendations?"
Not sure if this is exactly what you are looking for, but Analog and Asimov magazines feature short stories, but once or twice per year will serialize a novel. If you prefer mysteries, I imagine similar offerings are available for Ellery Queen and Hitchcock magazines.
There is a Fantasy magazine in the same format, but the name escapes me.
