Throughout the centuries angels have been featured in, among others, theological works on scripture; studies in comparative religions; works on art, architecture and music; philological studies; philosophical, sociological, anthropological, archeological and psychological works; and even a psychoanalytical study of the implications that our understanding of angels has for our understanding of sexual differences. This bibliography lists 4,355 works alphabetically by author. Each entry contains a source for the reference, often a Library of Congress call number followed by the name of a university that holds the work. More than 750 of the entries are annotated. Extensive indexes to names, subjects and centuries provide further utility.

From his first publication of hymns in 1707, common knowledge regarding Isaac Watts (1674–1748) often revolves around his hymn-writing legacy. Though Watts legacy as a hymnographer is significant, he also functions as a key transitional figure between the English Puritans and the Evangelicals during eighteenth-century English dissent. As a pastor, theologian, philosopher, and literary mainstay of his era, Watts' influence grew well beyond his early work in hymnody to impact scores of Christians on both sides of the Atlantic. Watts' approach to Christian spirituality is an area of his thought thats been unexplored. This book provides the first ever analysis of Watts' theological vision for the Christian spiritual life. In emphasizing the experience of holiness and happiness, Watts leans heavily upon his Reformed theological heritage to underscore how knowing and loving God are central to God's preparation of the soul for heaven.
