I have a substantial collection of reference books about Barbie doll and her world, but I simply COULD NOT do without this book! It is the most complete, chronological breakdown of Barbie & family dolls and that I have found. This book, in combination with Marcie Melillo's "The Barbie Book", will help the beginner and even the advanced collector to identify just about any Barbie family doll from any early (60's & 70's, primarily) era. It even goes into detail about dolls offered in successive years, and the differences in their manufacture, so that, for one example, you can tell to WHICH year your specific Growin' Pretty Hair Francie, a doll offered over a few years in the early 70's, belongs. The text accompanying the many, many photos is succinct and easy to understand, and while many photos are in black-and-white, there are quite a few pages of color photos as well, which detail much of Barbie's clothing across those early years. Well-executed, altogether. One might expect just such an excellent guide from Sibyl DeWein, who was a major player in the Barbie collectibles world until her death just a few years ago. I bought the book because she was a name of such renown & had written it (with a co-author/collector), and I was and am pleased to have it.
