Please be careful. It can be difficult to identify valid, peer-reviewed, authoritative journals in the mass of a business model that has publication offers popping up constantly in your email. Many appeals to the potential author appear, on the surface, to be scholarly, valid research organs of communication, but careful research reveals that the appeals are actually something else. Please ask your librarian for help or do the research yourself.


To determine if an offer to be published is the kind of high quality journal you seek, library scientists have produced some helpful resources. Take the title and any other information you have about the title and start your search. Trust, but verify.
