Cabell's Directories helps to determine what types of manuscripts journals typically publish. The index in each Directory helps match the characteristics of a manuscript to the topic areas the journal emphasizes and acceptance rate. The Directory also includes information on the style and format of most journals to further assist authors in organizing and preparing manuscripts. Furthermore, the Directory describes the type of review process used by the editor(s) of a journal, type of review, number of reviewers, acceptance rate, time required for review, availability of reviewers' comments, number of copies required and manuscript topics. Information on the journals printed and electronic launch dates and ISSNs are also provided.
