k . . .

I have a question, i have followed Ranma very much with the Anime, but have
been hesitant about going into the manga. Now i want to start getting them,
because thats the main heart of Ranma, but can someone tell me how many
there are? I mean, i hear stuff about different volumes, and multiple manga
per volume, and then i see these miniature books, and normal comic books, i
mean, whats what?

please lemme know
