Guidestar is a searchable directory that provides detailed information on many nonprofit organizations. It includes IRS-registered 501 nonprofit organizations that may accept tax-deductible contributions. Profiles of these organizations cover missions, programs, financials, leaders, and the IRS 990 filing from 1998 forward in most cases.

Guidestar is available remotely to all UNT community members. Non-UNT affiliated users can access Guidestar from a dedicated community computer station in Sycamore Library or Willis Library.
