Paperity

Paperity is the first multi-disciplinary aggregator of Open Access journals and papers, “gold” and “hybrid”. It:

gives readers easy and unconstrained access to thousands of journals from hundreds of disciplines, in one central location;
helps authors reach their target audience, disseminate discoveries more effectively and maximize research impact;
raises exposure of journals, boosts their readership and encourages new manuscript submissions.
Paperity is the way towards more efficient scholarly communication in all research fields, from Sciences, Technology, Medicine, to Social Sciences, to Humanities and Arts. Our ultimate goal is to aggregate 100% of Open Access literature, published in any place around the world, in any field of research.
