For educators, students, and persons looking for information about any period in American history will find the Gilder Lehrman Institute of American History Web site an excellent resource containing thousands of helpful materials ranging from the colonial period to the present day. The site is divided into three main sections: Resources by Period, Resources by Topic, and the Reference Room. Users looking through the Resources by Period area will find links to online textbook chapters, readings provided by professors from different institutions, and primary source documents. The Resources by Topic section contains similar information, organized around topics such as labor history, legal history, and family. The Reference Room contains other online resources such as links to music of different historical eras and audio recordings of speeches by important figures in American history. A fun feature of the site, and one that may be of interest to educators and students alike, is the Interactive History area, where users can submit questions to the HyperHistorian and take the 1885 8th grade examination test.
