Access for Students & Faculty

The Widener library combines world-class academic resources with spaces designed for focused study and collaborative research. Its specialised collections, rare book holdings, and access to thousands of academic journals and databases make it an essential resource for serious scholars. The library also supports digital humanities, data science, and emerging research methodologies.
Access & Membership
Current students and faculty have full access with their university ID. Community borrowing cards may be available for local residents at some university libraries — check the library's website for eligibility. Visiting researchers can often arrange temporary access by contacting the library in advance. Public access hours may differ from student hours, particularly during exam periods and summer breaks.
Widener Library Services
The Widener library offers high-speed WiFi, individual and group study rooms, computer labs, printing and scanning stations, research consultation services, and interlibrary loan for materials not held on-site. Digital resources include access to major academic databases like JSTOR, PubMed, and Web of Science, as well as specialised collections relevant to the university's research strengths.
Visitor Tip: University library hours change dramatically between term time, exam periods, and vacation. During finals, many university libraries extend hours to 24/7 operation, but access may be restricted to students and staff only. Summer hours are often significantly reduced. Always check the current schedule online before visiting, especially if you are not a university affiliate.
Did you know? University libraries in the United States collectively hold over 1 billion volumes. The Widener library contributes to this vast academic resource, providing students and researchers with access to knowledge that would cost tens of thousands of dollars to access individually through journal subscriptions and database fees.
