In the 1990s alone, more than 400 works on angels were published, adding to an already burgeoning genre. 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.

This exhaustive volume catalogs nearly three thousand demons in the mythologies and lore of virtually every ancient society and most religions. From Aamon, the demon of life and reproduction with the head of a serpent and the body of a wolf in Christian demonology, to Zu, the half-man, half-bird personification of the southern wind and thunder clouds in Sumero-Akkadian mythology, entries offer descriptions of each demon's origins, appearance and cultural significance. Also included are descriptions of the demonic and diabolical members making up the hierarchy of Hell and the numerous species of demons that, according to various folklores, mythologies, and religions, populate the earth and plague mankind. Very thoroughly indexed.
