The origins of the IMC's "Sister Libraries" Project can be traced to 1978, when a group of teachers in Cochabamba, Bolivia began an ongoing reading and writing workshop called the "Pedagogical Experiences Workshop." In 1990, the teachers of this workshop founded the only children's library in Bolivia, naming it Th'uruchapitas, or "Cheeks of Clay," referring to the chapped faces of indigenous children living in the harsh climate of the pampas.
Impressed with the group's success, Appalachian State University Library Science Professor Linda Veltze developed a plan to add to the Library of Th'uruchapitas' small collection of books. In addition to soliciting Spanish and bilingual books from publishers and government agencies, Dr. Veltze also applied for "Sister Library" status through the White House Centennial Commission. In 2000, the IMC became the only university library in the United States linked to a South American children's library, and ceremonial plaques were presented to the Appalachian State University Library, the Library of Th'uruchapitas, the city of Boone, and the city of Cochabamba.
