From original manuscripts and letters to sound recordings and birth certificates, archival information plays an increasingly important role in modern research. Libraries and the Internet have made finding information on a wide range of topics faster and easier, but not all information—particularly from primary sources—is available via local library branches or online resources. Using archival information presents its own challenges. Materials are often located in many different places: public or academic libraries, government agencies, historical societies, or museums. They are usually kept in secured areas where the public is restricted from browsing. This definitive guide shows novice and experienced researchers how to find archival information. It provides tips on how to use archival materials effectively and efficiently. Topics covered include government archives, science and technology collections, military archives, genealogical records, business and corporate archives, performing arts archives, and sports collections. Also provided is an overview of the world of archives, including archival terminology, how to contact archives, and archival etiquette. Whether searching for a noted author's original manuscripts, trying to locate presidential papers, or tracking down a repository of oral histories, Archival Information is an indispensable reference.
