Dear Collette, At a recent genealogy conference, I purchased Ohio Genealogical Research by Dr. George K. Schweitzer. It's four chapters are: (1) Ohio Background; (2) Types of Records; (3) Record Locations; and, (4) Research Procedure & County Listings. If you have an interest, let me know, and I will give you his address. It appears to be a self-published book. I paid $12.50 for it. I haven't had time to scan it yet, but it does seem to cover the basics. Bonne chance, Jane Miller
