JSTOR is a digital library founded in 1995 that provides access to millions of academic articles, books, and sources. It works with the academic community to connect students, faculty, and independent researchers with content. While most of its content requires a subscription, some older public domain materials are available for free. JSTOR offers various subscription options based on institution type and content access needed, and individual research subscriptions are also available. It provides 24/7 online access and enhanced research tools, as well as text mining support and usage reporting.
