This database is the most essential collection of written materials for historical research in American history from 1801-1819. It provides full-text access to nearly 4.5 million pages of 36,000 books, pamphlets, broadsides and other imprints published in the U.S. during this period. Gazetteers, almanacs, juvenile literature, chapbooks, hymnals, campaign literature, novels, slave narratives, spelling books, school readers, treaties, maps, atlases, advertisements, diaries, autobiographies, and much more are all included. Most of these materials were originally detailed in the bibliography compiled by Ralph Shaw and Richard Shoemaker. This collection, long available on microfiche, is made available here as a digital, fully searchable online database. It complements Readex's other Early American Imprints series of material from the period of 1639-1800.

This fee-based service provides a range of resources. There are a large number of secondary sources, including more than 2,500 scholarly journals, magazines, newspapers, and trade publications, with full-text access and searching capabilities available for approximately half. "Historical Newspapers" offers an enormous body of primary sources, including access to the following: The New York Times (1851–2001), The Washington Post (1877–1988), The Wall Street Journal (1889–1986), The Christian Science Monitor (1908–1991), and The Los Angeles Times (1881–1984). For recent history, there are articles from more than 500 newspapers worldwide from the 1980s to the present. These include specialized publications from the worlds of business, education, medicine, religion, and sciences and reference resources. ProQuest offers subscribers a variety of product "modules," so materials described above may not be available at all institutions.

Hundreds of thousands of documents spanning four centuries of American history are available in this large archive. Broadsides, ephemera, pamphlets, and booklets are available from 1639 to 1900. More than 1,300 newspaper titles, representing all 50 states, range in date from 1690 to 1922. U.S. Senate and House of Representatives reports, journals, and other documents are available from 1817 to 1980. Legislative and executive documents from the Early Republic are also included. The entire body of documents is keyword searchable, and, in addition, each collection can be searched and browsed individually. These documents shed light on many aspects of American social, political, economic, and cultural history, and can provide a valuable window into the daily lives of early Atlantic peoples. The collection of broadsides and ephemera is especially useful for exploring the history of printing in the United States, as all titles can be browsed by bookseller, printer, or publisher.
