Unfortunately there are some publishers offering publication opportunities but their publishing practices are not acceptable in academia. Some offer options for publication in non-existent journals, whilst others provide no peer-review or editing services or other added value. Some charge excessive article processing charges to authors. To find out who these publishers are, you can check the list provided on Tab "Predatory Publishers" or do a search on Google under "predatory publishers" and you will find a list.
Before publishing, just make sure that you are publishing in a reputable publication, by a reputable publisher, with proper peer-review, editing and other acceptable practices.
If any Wits staff or students are contacted by any publishers to publish their theses/dissertations or republish their articles, please contact Wits Scholarly Communications and Copyright Services Office (Denise.Nicholson@wits.ac.za) or Wits Legal Office (Dawn.Taylor@wits.ac.za) before publishing your work, as the intellectual property belongs to Wits University.
