THE MUMMY IN ANCIENT EGYPT: EQUIPPING THE DEAD FOR ETERNITY by Salima Ikram and Aidan Dodson is absolutely the best and most comprehensive book on Egyptian mummification. This oversized 352-page book covers  the full 3,000 years of Egyptian burial rites in depth: how mummies were made, wrapped, adorned and sheltered for eternity. Unlike other books which cover the subject in a fairly general way, Ikram and Dodson truly delve into the subject: both the text and the illustrations treat the reader to a thorough look at the subject. Separate chapters on mummification, coffins, sarcophagi, jewelry and amulets--not to mention wrappings on the mummies themselves--take the reader who may have a general knowledge of the subject to concrete examples and detailed descriptions and accounts related to the topics. 

I highly recommended this book for its scholarship and its exquisite art (485 photos and drawings--many very rare, or at least rarely published). If I could only have one book on the subject, this would be the one I would select. Ikram is a professor of Egyptology at the University of Cairo; Dodson teaches archaeology at the University of Bristol. They have organized their material well and written about it with flair. Ages 11-Adult (though younger children couldn't read it, they would appreciate much of the artwork).

Highly recommended.
