I have divided mine into Indian and California. But like you, my California Card room binders are full and getting fuller. I have thought about pulling out the illegals and putting them into my U.S. Illegal binders but I have some problems since I am unsure about the status of some of the older closed clubs--whether they were licensed or legal or not. I do know about illegal status of the Clover Club; the SS's and some others. So I do with California what I do with my other big collections--divide them by alphabet.
