According to Wikipedia, "....predatory open access publishing is an exploitative open-access publishing business model that involves charging publication fees to authors without providing the editorial and publishing services associated with legitimate journals (open access or not). "Beall's List", a report regularly updated by Jeffrey Beall until January 2017, set forth criteria for categorizing predatory publications and lists publishers and independent journals that meet those criteria. Newer scholars from developing countries are said to be especially at risk of becoming the victim of these practices..."
Predatory journals and publishers is a phrase coined by Jeffrey Beall, scholarly communications librarian at the University of Colorado at Denver. Beall is known for his list of predatory journals and publishers which he has maintained since 2008. The list has grown to thousands of journals and publishers that are alleged to have exploited OA publishing for profit. In an interview with The Chronicle of Higher Education, Beall said that "...predatory open-access publishers are those that unprofessionally exploit the gold open-access model for their own profit. ...they operate as scholarly vanity presses and publish articles in exchange for the author fee [and] characterized by a level of deception and lack of transparency; some publishers may misrepresent their location, stating New York instead of Nigeria, or claim a stringent peer-review where none exists." Some journal publishers send multiple messages to researchers with invitations to publish their findings and present them at conferences and pocket publication or registration fees while providing little or no review. Beall populated the lists based on 52 criteria he developed but the list was taken down in January 2017.
Some questions health librarians can share with researchers to assist
Does the publisher provide full, verifiable contact information, including an address and phone number?
Is the journal transparent about recognized experts with full affiliations on editorial boards? Ask board members about their experiences with the journal and/or publisher.
Does the journal display its policy clearly around fees? open access fees, and author fees.
Are authors bombarded by e-mail invitations to submit papers or to serve as editorial members?
Read the journal's published articles and assess their quality; contact past authors to ask about their experiences.
Is the journal transparent about its peer-review process; is it described; is the claimed impact factor correct?
Is the journal a member of an association that vets members, such as the Directory of Open Access Journals (http://www.doaj.org) or the Open Access Scholarly Publishers Association (http://www.oaspa.org).
Some questionable journals continue to appear in directories such as DOAJ and Cabell's thus do not use this as your only evaluation criterion. In fact, exercise your collections and critical appraisal instincts; if it looks questionable proceed with caution or dig deeper.

To determine open access journals that charge no fees
According to Wikipedia, Jeffrey Beall is a librarian and associate professor at the University of Colorado, Denver, known for his monitoring and criticism of predatory open access publishing. He makes no claims about the titles he lists; the Beall list is a useful starting point for debate but each title should be evaluated and investigated. If scholars publish in the wrong journal this will be detected by their peers on tenure and promotion committees. Every field has a range of journals and reaching the widest possible audience sometimes means that papers are submitted to journals at the top tier. Beall's titles fall into some of the grey areas around top tier-not top tier. Librarians can provide information about suitable/unsuitable places to publish and explain why we think they are; it is up to scholars and researchers to decide what to do with the information.
The Nurse, Author, & Editor journal has put together some guidelines for editors to determine if a journal is predatory or not. These guidelines came out of the INANE (International Academy of Nursing Editors) annual meeting this August. Jeffrey Beall was one of the keynote speakers and spoke on the dangers of predatory publishing. While intended for editors, the list can definitely used by authors, including non-nursing authors, too. You do need to register for a free account to view the article though.
