The Annual Cyclopedia was an American yearbook covering the years 1861–1902 by the New York publisher D. Appleton & Company. It was a comprehensive yearbook of events, obituaries and statistics, worldwide, with many articles written by experts, some of them signed. It was sold as an annual supplement to the New American Cyclopedia in 16 volumes, edited by George Ripley and Charles Anderson Dana, 1857–1863. When that encyclopedia was enlarged as American Cyclopedia (1873–1876), the Cyclopedia started a new series. Sets are held in major libraries, and some volumes are online.
