There are tons of web sites where you can get some information and most larger libraries have a few good books on the subject.
The best thing, in my opinion, would be to find a pro shop that deals with traditional archery gear. They would be able to help you and, usually, have a few bows you could try, maybe even some used equipment, to start out with. Most importantly, they can put you in touch with other traditional shooters, a club, or, maybe, custom bowyers in the area. With this information, you might be able to shoot a variety of different bows.
Some companies, like Black Widow, have a plan where you can try a bow before you buy one (basically, you buy it, shoot it and, return it for a refund).
Do the research, shoot some bows, and don't get over bowed to start out. There's nothing more discouraging that blowing a grand on a custom take down with an extra set of limbs and finding that the old used Puma hanging in your garage (the one you bought used for $25.00 25 yrs. ago) shoots better for you.
