Race has become a central topic this election year, with Hillary Clinton giving a half hour speech on it last week -- but a shorter message can be just as powerful. A few weeks ago a poster board went up at the Denver Public Library's central branch, and since then it's been filled with messages like: "Many colors inside. Only white outside." And "'A well-spoken black man,' etc."

The messages are part of a local installation of The Race Card Project, created by former NPR host Michele Norris. This fall several branches of the library, including the one in Park Hill, are opening their own Race Card displays. Reference librarian Robin Filipczak is managing the project and spoke with Colorado Matters host Nathan Heffel.
