Actually it's quite feasible using LaTeX, it's just a pity that the learning curve and the technical involvement are higher than when using DTP tools like Adobe InDesign.
This explains why few people are willing to involve the required amount of time and energy into mastering LaTeX for such kind of projects, and consequently why few introductory material is available on the subject.
One notable exception is the recent workshop given by Dominik Wagenführ at Ubucon 2009 in Göttingen. Its proceedings are freely available a the bottom of the page, as well as the related source code. It's all in German but fairly easy to understand and very educational, so I'd recommand you to study it.
