The editor has justified the publication of yet another new text on the basis of three innovations. Most obvious is the consideration of obstetrics and gynecology in one volume. This reflects the combination of responsibility for care and training in both fields within a single department in most American institutions. The resulting presentation avoids duplication of material, from the students' point of view a beneficial efficiency. Secondly, the text has contributions by a distinguished faculty representing more than 30 training centers, thus assuring authoritative treatment in all aspects of the classic curriculum. It must be pointed out, however, that this may also occur in texts enjoying single authorship.
Finally, the editor has succeeded in expanding the material beyond that typical of texts in this field. This he accomplishes by acknowledging that related specialties as well as pertinent fields of basic science have their impact on informed obstetrical and gynecologic practice.
