I will admit to reading this book with a feeling of trepidation. The first edition, published in 1979, is a classic in the museum studies literature, and by far the best single book about museums ever written. Although the original was outdated, there is always a huge risk when you mess with a classic. But have no fear, Mary Alexander has done a fantastic job of updating her father's book. The new Museums in Motion remains the single best book about museums, a terrific introduction for neophytes, and a wonderful refresher for experienced museum professionals. M. Alexander has kept her father's voice and lively style throughout the book, making it also an excellent book to had out to board members and the general public who wish to better understand museums. It is not a comprehensive history of museums, nor a how-to guide, but rather an explanation of what museums are and how they function. The "Challenges" sections that M. Alexander has added to each chapter provide simulating points for discussion at any level of museum expertise or interest. Museums in Motion is both informative and charming, easy-to-read and stimulating.
