Antique Cook Book

I have started collecting old books. This is what got me started. I look for books from the 1900 back. My oldest for now being 1860 The Marble Faun By Nathaniel Hawthorne. A. L .Burt, Publisher. I really don't know how to collect them or what to do with them later. Please if you can give me some pointers on book collecting please do so. For now it's anything before 1900 and First Editions only I learned later.
