Unfortunately, my experience with groundfighting consists of one Brazilian jujitsu. seminar about 6 years ago and a brief introduction to leg sweeps in kungfu last week (which is not really groundfighting per se).
I've tried searching for "jujitsu fiction" "martial arts fiction" and "jujitsu techniques" and variants thereof and have come up with (a) fetish porn, (b) overly technical martial arts websites, and (c) stories about karate, which aren't helpful. I think the ideal research material would be fiction about jujitsu or judo written for a non-martial arts audience (and thus light on the Japanese technique names), but I'm coming up blank.
Any help would be greatly appreciated.
