This is a very interesting book to read. Can't say much about the author or really much about the Kaufmanns but even without that information I can say that this book is a really excellent resource. Starting with the structure of the book itself it is divided into five sections. The first section relates with kitchen related topics including grow to make cider, red wine vinegar, make eggs, brew coffee and of course as said on the cover to shuck an oyster (even though I despise shellfish this can be useful).
The second one involves outdoor survival like smoking food, starting campfires building shelters, reading the sky, crossing a stream, and yes splitting wood. The third section is various home related stuff like composting, making candles, and caring for copper. The fourth section is related to Gardening like pruning, and building birdfeeders. The fifth and final section is related to personal grooming like caring for denim. mending clothes and making soap.
As for criticisms there's not much to say. It's a pretty solid book filled with a lot of stuff that will make you more self-sufficient. And the graphics shown are pretty useful though there is a strange inconsistency with regards to the art style, from actual photos to black and white sketches, grey scale images, colored pictures, and even Nintendo 64/ original PlayStation 3D models. Very odd and I'm not sure why. It's 217 pages long but feels much shorter due to effective use of simple language and many pictures. Overall worth a read
