Review of the hardback: 'The relatively familiar material … covers somewhat more than a third of the book … the rest of the book's contents … is less familiar … I feel that [the authors] have … made a good choice … the exact solutions they discuss are surely important … for a person who wants to work in the field …As a reference on a wide selection of exact solutions, with geometrical and physical detail not found previously in one place, this book is a very useful companion.'
