If you're really "in" to the Dead Sea Scrolls, then you won't want to miss this volume. The subtitle ("The Parting of the Ways Between Qumran and Enochic Judaism") really only tells part of the story; Boccaccini devotes a lesser portion of this book to a quite reasonable hypothesis of the origins of the Essene movement in what he calls "Enochic" Judaism. The majority of the book is devoted to descriptions of the life and literature of the Essenes, and includes a collection of secular data on them (from Josephus, Pliny, Philo, etc.). As such it is an excellent reference and complements (even as it sometimes duplicates) Pate's volume noted above.

Readers will note that Boccaccini is of the "liberal" persuasion (his brief treatment of Daniel assumes, but provides no arguments for, a Maccabeean date), but this does not affect the bulk of his work. Significantly and appropriately, he devotes all the attention to the likes of Eisenmann and Thiering that is deserved -- i.e., none. This is a sane and sober work that will be useful to the serious student of the DSS.
