For September 15, 2008: Learn about Henry David Thoreau and his writings at The Thoreau Reader, a project "in cooperation with The Thoreau Sociey" (a worthy resource in its own right) and a comprehensive website featuring online versions of many of his books and lots of links and annotations about his literary works. You may want to use excerpts from the material as introductory pieces with elementary and middle school students, especially if you are reading books about Thoreau.
