This volume is a delight to the economist. The book is clearly destined to be a classic, perhaps one of the few emerging in that role rather than growing into it. The reader cannot fail to be impressed by the size of the task to which the authors committed themselves, by the authors' ability to treat the broad sweep of a century of monetary history without being overcome in the mass of detail that they carefully examine, by the originality and scholarship that are everywhere displayed, and by a host of other considerations most of which are conveyed by the word "classic".
