The present bibliography grew out of a need to provide a basic working list for participants in a conference held at the University of California, Davis in April of 1988. Originally consisting of publications of conference participants, it grew from a specialized working document into a more comprehensive monograph bibliography, at first with a simple snowball method; and subsequently, with the aid of two major bibliographic utilities: the University of California's system-wide online catalog (Melvyl), and RLIN (the cataloging database of the Research Libraries Group).
