The Congressional Serial Set contains most reports to and from Congress. It is therefore a source of hundreds of thousands of primary sources on American history and much more (for example, a report on Maya heiroglyphs). The volumes also contain maps, photographs, and hand-colored illustrations on many topics.
Western Libraries has a few hardcover volumes, but it also has full-text access to the Serial Set from 1789 through 1969. It is part of the ProQuest Congressional database.
