Online sources and references are great, but sometimes an actual book is still a good idea ;-) Ancestry's Redbook provides an overview to various state and local genealogical sources for the United States. I co-wrote five chapters of the book (Illinois, Indiana, Ohio, Iowa, and Minnesota). There is more information about the book on our site. It is a good reference and if you watch the sales at Ancestry.com (the publisher) you can occasionally get a better price.
