Can anyone suggest some information sources or classes about bike fitting?

I'm happy with how I fit on my bikes, and much of what I do know was learned through correcting my own fit issues over time. But now I'm working at a bike shop part time, and want to become more skilled and knowledgeable in order to better serve my customers. Especially the women.

The guys I work with mean well and provide good service overall, but aren't accustomed to thinking about fit from a women's perspective. (One of them was shocked to learn that I ride a ~49cm frame, even though I'm 5'5". *grins*)

Thanks in advance for your help
