All numbered Extension publications must undergo a formal review process. Special bulletins and miscellaneous publications should undergo an internal review prior to receiving an Extension publication number. Bulletins and Circulars go through a more rigorous review process and should be refereed and reviewed by internal as well as outside reviewers prior to receiving a Extension publication number.
Bulletins represent a major writing effort.
Bulletins address different individual topics in a particular discipline or a series of individual discipline subjects for a specific commodity with references. An Extension circular is a publication that is more narrowly focused than a bulletin. A circular is a treatise of one subject in a limited stand-alone form with references. A series of Circular topics that have a common theme may be compiled to make up a Bulletin or components of a Special Bulletin if reviewed and approved by the reviewers. These publications are generally large handbooks on subjects or issue-related materials.
