Many publishers are members of trade groups or publishing organizations. Some of the best known of these groups are listed below. In addition, a link to Cabell's, a well-known directory of journals, and a link to Journal Citation Reports, are provided. Use these resources to help you identify best places for you to publish.
Note: Several organizations listed below--DOAJ, OASPA, and WAME--helped develop the "Principles of Transparency and Best Practice in Scholarly Publishing" that can 1) assist authors in evaluating publishers and publications, and 2) help potential editors and reviewers make informed decisions about service opportunities.
For monographs, find out if any of the publisher's books have won awards. Also, look for book reviews of their titles in relevant databases.
For further assistance, talk to your subject librarian. Subject librarians can suggest references that will help you identify and evaluate publishing opportunities, such as The Directory of Small Press & Magazine Editors & Publishers and other publishing directories.
