Duplicate "Manufacturers Page" function for different things

How difficult would it be do to this or if there's already an extension that does do this that would be great.

Basically (for example) if I want:

Manufacturers (included now)
Series
Genre

Right now I just have the manufactures page, is there any way to basically just duplicate the manufacturers page to use it in the same fashion but for other things? Basically a way to organize and narrow down searching for things for a store with a lot of products and variables.

Thanks in advance to any replies / help!

It seems there MUST be a hack written in a post somewhere, or an extension. I"m going to look around a bit before I spend some time on doing it for you.

I found some links that "may" help" maybe not:

Hey that's not what I'm looking for but thanks for looking into this.
