The indices which follow are the editors’ efforts to organize this bibliography and to provide the reader with major classifications of the citations. These indices, as with the bibliography as a whole, are aimed at giving the reader only an entree into the field. The sources sited, as well as their annotations in this bibliography, may include additional information not indexed here. Therefore, the reader is well advised to leaf through the bibliography as a whole for any topic not indexed. For example, since in virtually every citation women figure prominently, the role of women in spirit possession and spirit mediumship is so pervasive as to render an index of it redundant of the bibliography as a whole. The decision to index the specific topics below is based on the editors’ assessment of professional interest in these topics, and on a significant number of relevant entries.
