The National Humanities Center has recently added a second guide to its TeacherServe site (originally reviewed in the November 7, 1997 Scout Report). Nature Transformed: The Environment in American History contains a number of essays specifically tailored to classroom use. These are organized in three thematic sections: Native Americans and the Land, Wilderness and American Identity, and The Use of the Land. Each essay also features a section on guiding student discussion, a brief overview of the relevant historiographical debates, and links to related online resources.
