The late William L. Holladay (1926-2016) was professor of Old Testament at Andover Newton Theological School in Boston. In 1993 he published a marvellous book, The Psalms through Three Thousand Years: Prayerbook of a Cloud of Witnesses (Augsburg Fortress). I purchased this book eleven years ago, and, while I read bits and pieces of it afterwards, only now have I got round to reading it from cover to cover. Indeed it is one of the most extensive books in English about the biblical Psalms, covering everything from authorship, sources, compilation, canonization, and liturgical use by Jews and Christians over the centuries. A full review of this encyclopaedic treatment would require more space than I can give to it, but I think it worthwhile to highlight some of the more interesting elements that make it such a rich treasure of information.
