The Library of Congress is now accepting applications for all six of their 2010 Summer Teacher Institutes. The summer institutes are designed to help participants develop classroom activities that incorporate primary documents, understand legal use of digital documents, and learn how to access materials cataloged by the Library of Congress.

The Library of Congress Summer Teacher Institutes are free to attend, but you do have to provide your own lodging and meals. The institutes are four days long. There are sessions being offered in May, June, July, and August. You can read more about the institutes and apply here. You can access materials from previous institutes here.

If you’re not able to attend on the Summer Institutes you can explore three self-directed online professional development modules.
