Authors Beware of Predatory Online Publishers
Predatory journals are from unscrupulous Open Access publishers who exploit the author-pay model by soliciting submissions from as many scholarly authors as possible in order to collect a high volume of article processing fees.
We recommend our Authors works with a publisher:
Stop Predatory Journals is a site built by an independent group which wishes to remain anonymous. The list of journals they share can provide you with insight; however, if you still question the journal quality or the intent of the publisher, please contact us.
The National Institute of Health (NIH) requires that all researchers funded by the NIH submit to the National Library of Medicine’s PubMed Central an electronic version of their final, peer-reviewed manuscripts upon acceptance for publication, to be made publicly available no later than 12 months after the official date of publication.
View the MSK Library's NIH Public Access Policy LibGuide providing information and guidance for policy compliance.
The Library currently supports the following institutional memberships with open access publishers.
The following are a few Open Access/Public Access repositories. If you would like to see one added to this list, please contact the LibGuide author.
