'Professor Baker's second edition is a thoroughly welcome volume, and highly recommended to new readers. As for those old enough to have a copy of the first edition on their shelves, it is likely that the ninety pages of updated and judiciously selected references would on their own justify the investment. More broadly, however, … perusing the second edition avails the opportunity to see, through the eyes of a trusted guide, where and how our craft has evolved since the turn of the century.'
