Which Wikipedia project provides free access to paywalled research articles?

The Wikipedia project that provides free access to many paywalled research resources is The Wikipedia Library.

The project was created to help Wikipedia editors consult high-quality sources that might otherwise require expensive subscriptions. Through partnerships with publishers, databases, and libraries, eligible contributors can receive complimentary access to selected research journals, newspapers, books, and other reference materials. This helps editors verify claims and improve citations.

The Wikipedia Library does not make every paywalled article in existence freely available, and it is not a piracy service. Access depends on the participating provider, the resource involved, and the user’s eligibility. Some benefits are available to established editors who meet activity requirements, while other resources may be open to a wider audience.

It is also distinct from ResearchGate, which is a scholarly networking and sharing platform, and from tools such as Google Scholar, which helps users discover academic literature. The Wikipedia Library supports Wikipedia’s core sourcing principles by connecting contributors with reliable publications rather than replacing publishers’ access systems.
