Assignments will be matched to volunteers based on their stated research interests. In certain cases, volunteers may receive assignments that do not directly match the interests indicated below; this would occur if the research topic is multidisciplinary. We ask that article submission volunteers and book proposal volunteers please return reports within two weeks of receiving the assignment. Book manuscript volunteers will be expected to return reports within six to eight weeks. Complete information on the responsibilities and expectations for reviewers are listed in the Publication Ethics section of the CGRN webpage: http://cgnetworks.org/journals/publication-ethics.
