This list of potential, possible, or probable predatory scholarly open-access publishers was created by University of Colorado Denver librarian and researcher Jeffrey Beall. There is an "original list" as well as an "updated list".
Ulrichsweb (Ulrich's Periodicals Directory) is a database that SCU library subscribes to. Ulrich's will tell you if a journal is still in print, available online, where it is indexed, and most critically, what type of journal it is (scholarly, trade, popular, etc.). Ulrich's does not tell you if a journal is good or bad. It just gives you classifications and you make the final judgement.

Warning Signs of Predatory Journals
Tactic
How to Recognize
Solicitation
Suspect journals aggressively solicit scholars to submit papers. The solicitation may come as spam or individual emails. Legitimate journals usually do not solicit authors but instead have the authors contact them.
The journal agrees to publish your article for a fee before reviewing it.
Peer Review
A claim that a journal peer reviewed is not enough. Almost all predatory journals claim to be peer reviewed.
The stated time for peer review is extremely short.
You are asked whom you would like to review your work.
Impact Factors
Be wary of journals that cite bogus impact factors, such as the GIF (Global Impact Factor), Index Copernicus Value, Citefactor, or the UIF (Universal Impact Factor). Some may falsify legitimate impact factors. Impact Factors can be verified via Web of Science, Dimensions or Google.
Editorial Board
Members of the editorial board lack qualifications in the field.
Different journals by the same publisher have the same editorial board.
Predatory journals will sometimes solicit well-known scholars to join their boards in order to lend credibility to their journal but don't let them make decisions. (How you would make this discovery even with good due diligence is hard to imagine.)
Listing academics as members of editorial boards without their permission and not allowing academics to resign from editorial boards.
Indexing
The journal is not indexed in the major indexes in the field as well as general indexes, even though it might claim to be.
Some journals falsely claim to be indexed by Thomson Reuters.
