My favorite book on my shelf is Ancestry's RedBook. I use this book on almost a daily basis. I will never get rid of my hardback version, even though you can now view it for free on Ancestry.com.
Every time I try to view the online version of RedBook I find that I can not read the section where the column format was used. That's the part I use most often. It will tell you when a county was created and what the parent county was. It will tell you from what date Birth, Marriage, Land, Death etc. records were kept. And it will tell you where to write for those records.
The other part of the book that is formatted in the regular paragraph type formatting comes through my computer just fine. But I use that part less often.
