One of the hottest terms among public librarians today is "content creation," which involves stuff that library patrons make instead of simply use in a library context. Videos, music, fiction, paintings, 3D printed materials, websites--all these are made in public libraries, and will increase in popularity as more libraries shift from purveyors of content to facilitators of creation. Libraries are becoming "incubators" of art, ideas, economic benefits, and community benefits. A library seething with creative energy can shock some traditionalists, who still see the library as a quiet place to read a book. Yet the mission of many public libraries is not only to inform via printed or multimedia materials but also to connect ideas and people, to build communities, and to offer transformative experiences to all by bridging opportunity divides. In light of the "library=transformation" model, art programs are a natural fit. And art programs require teaching artists to lead them. In this article the author looks at the librarians' perspective on hiring teaching artists, running successful art programs, and ways in which librarians and artists can build mutually beneficial partnerships. This article focuses on teen art programs, because few libraries currently have as comprehensive an adult art focus as they do for teens. The phenomenon of adult or all-ages art programming in libraries still appears sporadic or centered in large urban libraries. Teaching artists can use the data and discussion of this research to focus their practice in a public library setting. The author offers recommendations for getting in on the library program action, suggests ways to support the public library's goals and mission, and describes how libraries are supporting teaching artists in particular, and the arts in general.
