A technical book that will constantly be a resource for me as I continue to work on becoming an accredited genealogist. I own this book and it's a good thing because I will constantly need to reference it!
I have been doing genealogy research for well over a decade, and I have to say that one of my biggest problems by far is my lackadaisical approach to citing sources. It's not that I don't think citing sources is important. It's extremely important. I just get sidetracked when I'm researching and don't always write down where I found a particular document or fact.
This book is a wonderful resource for people like me. Take this book with you on your library trips! If you use the information presented in the book every time, you won't have to duplicate your work to go back and document your sources after the fact.
