Should I use CORE (core.ac.uk)?

The world's largest collection of open access research papers - core.ac.uk

Analyzed September 19, 2026 · 1 month ago

Use it if you need free full-text academic papers — it's the largest open access aggregator with a developer API. Skip it if you need paywalled journals or just want quick everyday searches; Google Scholar covers that better.
