The National Language Resource Centers are an excellent source of resources for all areas of the language learning field. Below is a short description of the initiative and links to the main site as well as the various centers.
"In 1990, the Department of Education established the first Language Resource Centers (LRCs) at U.S. universities in response to the growing national need for expertise and competence in foreign languages. Now, twenty-five years later, Title VI of the Higher Education Act supports sixteen LRCs, creating a national network of resources to promote and improve the teaching and learning of foreign languages. LRCs create language learning and teaching materials, offer professional development opportunities for language instructors, and conduct and disseminate research on foreign language learning. All LRCs engage in efforts that enable U.S. citizens to better work, serve, and lead."
