When I bought the last edition of this book it was a revelation: intelligent reviews of well-selected internet sites, together with sensible advice about how best to use your computer in building up a family history, plus updates of the review via the Good Web Guide website. However, the web moves on, and particularly in family history where there has been an explosion in both official sites and ones provided by altruistic enthusiasts. The new edition reflects this, with about three times as many sites reviewed as in the first edition, and many more headings to help you navigate your way through the book as well as the web. The short introductory pieces are full of good advice to encourage you to explore areas that you may not previously have considered. It is a wonderful book, and well worth buying even if you have the first edition.
