Challenges to Materials at Colorado's Public Libraries

Each year Colorado libraries report data for challenged materials in the Colorado Public Library Annual Report. Library staff respond to a follow-up survey to provide details about these items, including the items' formats, the reasons for the challenges, and the resulting outcomes. This information is tracked annually and is also reported to the American Library Association (ALA).

The following sections present these data in a variety of formats, from the numbers reported on the Annual Report, to the details provided in the follow-up survey.

LRS is part of the Colorado State Library, a unit of the Colorado Department of Education. We design and conduct library research for library and education professionals, public officials, and the media to inform practices and assessment needs. We partner with the Library and Information Science program at University of Denver's Morgridge College of Education to provide research fellowships to current MLIS students.

This project is made possible by a grant from the U.S. Institute of Museum and Library Services (IMLS).
