From a DOAJ News Service Article:
People think that DOAJ exists to index all open access journals. A journal can only be indexed if it passes all of our criteria.
The Directory of Everything open access would be a wonderful thing but of how much use would it be? DOAJ understands that users want: advice on where to publish; guidance on the reputation and credibility of a journal; peer-reviewed open access content published by quality journals. We serve a community who are interested in finding places to publish or read research for DOAJ-approved journals.
Of course, there are arguments that seeing all the open access research is better than only seeing a selection of it, but for sites which do this, where are the quality filters?
The article goes on to discuss:
- What defines an open access journal anyway?
- DOAJ compared to SCOPUS and Web of Science
