Before publishing in an Open Access Journal you should consider the following criteria:
The advent of open access publishing has resulted in the removal of printing barriers. Now assembly and dissemination of information requires little more than Internet access. Unfortunately, this has led to a proliferation of open access publishers with little or no subject expertise and of questionable repute. Scholars and researchers may receive email solicitations for fee-based paper submissions to journals that make false or misleading claims about the stringency of their peer-review process, members of their editorial board or indexing status.
Predatory publishing is a publishing business model in which authors are charged a publication fees and not provided the editorial and publishing services associated with legitimate journals.
