Credo is a great reference research center online.
The library subscribes to Credo, a web-based information resource which includes full text magazines, newspapers and reference tools. You can search it from any computer with Internet access - at home, work, school or at the library.
Access to Credo is made possible through a partnership between the State Library of Iowa and Iowa's Area Education Agencies. Primary funding is provided by the State Library using federal Library Services and Technology Act dollars.
