Covers over 1,100 periodicals published between 1740 and 1940. The journals cover three broad periods: America's transition from a British colony to an independent nation; the first 60 years of the nineteenth century, the golden age of American periodicals; the Civil War (1861-1865) and Reconstruction (1865-1877) eras. Deriving from the acclaimed American Periodicals Series microform collection, APS Online features over 1,100 periodicals spanning nearly 200 years-from colonial times to the advent of American involvement in World War I. Titles range from America's first scientific journal, Medical Repository, to popular magazines like Vanity Fair and Ladies' Home Journal, and include coverage of literary and professional journals, children's and women's magazines, and general interest magazines.
