The series presents materials in two fields, the history of economic thought, and the methodology of economics, both broadly considered. The main annual volumes present articles comparable to what one would find in a journal, except that long pieces are welcome. Also presented are review essays on new works in the two fields, some of which are multiple reviews; plus occasional mini-symposia. The archival supplements present hitherto unpublished materials - lecture notes, papers, longer manuscripts, correspondence, etc.- of interest in the two fields.
