According to the Library of Congress, "Primary sources are the raw materials of history— original documents and objects which were created at the time under study. They are different from secondary sources, accounts or interpretations of events created by someone without firsthand experience."
One of the best ways to discover the perfect source for your topic is to browse the library stacks by call number range. Each call number range represents a particular subject and all of the books on a particular topic will be located in the same general area on the shelves.
