There are a variety of ways to find out an author's credentials. Often it is found within the publication as a paragraph at the beginning of a journal article. If it is a book, this information is usually found on either the book jacket or inside back cover. If more information is needed on an author, you may need to find a biographical reference source such as "Contemporary Authors" or "Who's Who in America". Many authors also have websites that will list their credentials which can be found by searching for the author or by checking their Google Scholar author profile. Another way to check their credentials would be to search the person and their place of employment.
