"Tools of the Trade" was conceived by Lowell Edmunds as a bibliographic guide for graduate students and others interested in furthering their knowledge of the Roman world. When the expansion of scholarly resources and the growing capabilities of web-based publication made a second edition desirable, Professor Edmunds decided to divide the project into thirteen discrete bibliographies, each with its own editor/compiler.At this point, the project was passed on to Sander M. Goldberg of UCLA, who has assumed responsibility for editing the final documents and posting them on this site. The content and form of each bibliography has been determined by the subject editor, who is identified in the heading for each document.
