The volume contains the acts of the Colloquium Biblicum Lovaniense on the Composition of the Book of Psalms that was held in Leuven on 5-7 August 2008. Together the forty-four essays, many of these by first-rank experts in the field, offer an impressive survey of current research on the Book of Psalms, which is here primarily studied as a composition in its own right. Several contributors discuss methodological issues and various theological and redactional aspects of the Book of Psalms as a whole. Others offer an analysis of larger sections of the Psalter or of a specific Psalm within the broader perspective of the Book. Among the contributors are J.-M. Auwers, W.P. Brown, B. Doyle, E.S. Gerstenberger, S.E. Gillingham, F. Hartenstein, F.-L. Hossfeld, B. Janowski, K. Seybold, H.U. Steymans, J. Trublet, H. van Grol, and Y. Zakovitch. Erich Zenger, the President of the Colloquium and editor of the book wrote the opening address entitled "Von der Psalmenexegese zur Psalterexegese". He was still fully engaged in correcting the proofs of the congress proceedings when he was overtaken by death. This volume is a tribute to him.
