This book is good if: you are a genealogist NEW to the net. A lot of ground is covered, in terms of what kinds of software is needed (over an above thevenerable genealogical database), as well as how to act/speak/do online.
This book is bad if: you've been online for more than a week. Too much ground is covered... well... look at theparagraph above... :)
I've found that some of the information she presents is a bit dated, but notso much so that a new user will terribly embarrass themselves by relying on it.
Overall, formyself (as a computer consultant of 15+ years) it did have some information to impart. Notnecessarily enough to make this a "must have", but worth a read and recycle.
