This volume contains 15 of the papers read at the Fifth Meeting of the IOQS, celebrated in Groningen 27-28 July, 2004. The meeting focused on the identity formation of the group or groups represented in the Scrolls, explored issues of self-definition of Jewish groups in relation to, or in reaction towards other groups within Judaism ("sectarian" identity, inner-Jewish discourses and polemics), and inquired into the development of Jewish identity vis-a-vis other non-Jewish persons, groups or peoples as reflected in the Scrolls.

Qumranica Minora I: Qumran Origins and Apocalypticism brings together the author's much discussed articles on the so-called "Groningen Hypothesis" (an hypothesis about the origins of the Qumran Community in relation to the parent Essene movement and Palestinian apocalyptic movements), as well as a selection of his most important essays on Early Jewish and Qumran apocalypticism. The third part of the book consists of surveys of the history of research on the Dead Sea Scrolls. The volume includes English translations of essays that were originally written in Spanish and French.
