Readership, prestige, availability, subject scope, peer review process and acceptance rate should all be considered when choosing a journal.
Your colleagues, instructors and advisors are excellent resources to help you identify journals that are appropriate for your article. You may also want to consider submitting to one or more of the journals that you read in the course of your research.
You may also read of a "Call for Papers", a method used by publishers to collect articles, conference presentations, and book chapters for potential publication. While many calls for papers, conference presentations, etc. are from legitimate publishers, an increasing number are from predatory publishers. See our guide on Predatory Publishers.
