As part of the Library of Congress American Memory series, the CAL Collection of American English Dialect Recordings has been digitized and is now accessible online. This collection of interviews and other speech recordings, primarily from dialect research and oral history projects, provides a centralized source of North American dialect samples, preserving valuable linguistic resources that might otherwise be lost. The collection was donated by CAL to the Library of Congress in 1986 and has been accessible only by personal visit to the Library since then.
his web site was designed for EFL (or ESOL) teachers but of course, it's open for everyone else to have a look around (if you want).
* The site's main purpose is to offer some of the old TEFL work-sheets that I've made and that I hope you might be able to use in your classes.
