Book excerpt: The Dead Sea Scrolls are one of the most important archaeological discoveries of the last century. They have great historical, religious, and linguistic significance, not least in relation to the transmission of many of the books which came to be included in the Hebrew Bible. This companion comprises over 70 articles, exploring the entire body of the key texts and documents labelled as Dead Sea Scrolls. Beginning with a section on the complex methods used in discovering, archiving and analysing the Scrolls, the focus moves to consideration of the Scrolls in their various contexts: political, religious, cultural, economic and historical. The genres ascribed to groups of texts within the Scrolls- including exegesis and interpretation, poetry and hymns, and liturgical texts - are then examined, with due attention given to both past and present scholarship. The main body of the Companion concludes with crucial issues and topics discussed by leading scholars. Complemented by extensive appendices and indexes, this Companion provides the ideal resource for those seriously engaging with the Dead Sea Scrolls.
