This book provides a great overview of the varying collections housed in the British Museum, and provides details which are perfect to enhance a visit. It gives an explanation of how it all began followed by sections on the different collections. There are many photographs in both colour and black and white which help to illustrate the details in the text.
I found this book to be very interesting after seeing the exhibits, but I think it would be interesting all the same without having been so close to the artifacts. If you wish to learn details on something in particular then maybe this isn't for you, but for general information and interesting titbits its great!
