OA.mg · Open Access for Everyone · Download and read over 240 million research papers | WarmIndex

OA.mg is a specialized search engine for Open Access academic papers, indexing over 250 million papers to enable free downloads and reading for researchers worldwide.

🚀 Overview

OA.mg solves the problem of discovering and accessing Open Access research papers, which are often publicly funded but scattered without a central hub. Despite initiatives like Plan S making more papers OA, there's no easy way to find them all in one place.

It's built for researchers, students, academics, and the scientific community who need fast, free access to papers without paywalls.

The team behind Citationsy started OA.mg in 2022 after users demanded better paper search and download tools. Built in Stockholm, London, and Seoul, it's designed from the ground up to improve the research process using technology, promoting Open Access for everyone.
