This book is well organized and takes the time to explain the different concepts and needs of the beginner when starting the family tree organization and search. I was very fascinated with chapter 20 on "uncovering your genetic roots." As it may not be a specific as you assume.
Keep in mind no book can really be "everything" on a subject. However this one is a great addition to your repertoire. I am using it in conjunction with "Family Tree Maker 2011 Deluxe" by Nova Development US.
