This book is far more comprehensive than the pocket version and is very useful for those areas where my knowledge is limited such as trees and plants, operas etc. There is also good cross referencing between subjects.
A friend of mine had this book. When I looked through it I found most of the patterns to be well laid out so I decided to buy a copy for myself.Because most of the patterns are usuable it represents very good value for money. The instructions are very clear.
