For those desiring to read the Psalter in the Vulgate of the early church, this book is invaluable. The selected psalms are accompanied by extensive notes, explaining the Latin in terms of the Hebrew from which they were translated. For example, one aspect of Hebrew verb forms(completed vs. uncompleted actions) explains how the Latin translation can be either present or past tense. There is also a brief introduction describing the early history of the Latin Psalter text. The major disappointment of this book is its size; one wishes the author had annotated the entire Psalter, not just a few dozen psalms. In his introduction, LaDoceur alludes to just such a future project, but apparently it is yet to be realized.
