दुनियाभर के repositories से open-access पेपर्स इकट्ठा करने वाला aggregator — किसी paywalled आर्टिकल का फ्री PDF ढूंढने के लिए पहला अच्छा पड़ाव।

Built by the UK's Jisc and the Open University, CORE aggregates open-access papers from repositories around the world, a good first stop when a paper you want is paywalled elsewhere. Coverage depends entirely on what repositories have deposited, so a free copy isn't guaranteed even for papers that do have one somewhere.
