This book has been my "bible" on the subject of oriental rugs for about 5 years. It has been a source of knowledge and great pleasure as I have learnt more and more on this fascinating subject and purchased many rugs in the meantime. It never stays in the bookshelf very long, as I am frequently referring to it as the rug buying "bug" hits me. The book is comprehensively illustrated and has detailed information on subtleties of pattern design, which help in the identification of different rugs, even within a single district. I cannot recommend this book too highly as an attractive and informative book for novice or experienced rug lovers alike.
