Publication Quality + Evaluation

There is no one standard definition of what constitutes a "predatory publisher," but generally they are those publishers who charge a fee for the publication of material without providing the publication services an author would expect such as peer review and editing (commercial and non-predatory publishers also often charge authors fees, though they should be more transparent about what purpose those fees serve.) Such a business model aiming for quantity over quality perpetuates bad research in general and exploits both the Open Access publishing model, and academics' need to publish to further their careers.
