New American Cyclopædia
encyclopedia created and published by D. Appleton & Company

The New American Cyclopædia was an encyclopedia created and published by D. Appleton & Company of New York in 16 volumes, which initially appeared between 1858 and 1863. Its primary editors were George Ripley and Charles Anderson Dana.
The New American Cyclopædia was revised and republished as the American Cyclopædia in 1873.
Overview
The New American Cyclopædia was a general encyclopedia with a special focus on subjects related to the United States. As it was created over the years spanning the American Civil War, the focus and tone of articles could change drastically during its production; for example, Jefferson Davis, the future president of the Confederate States of America, was treated at length as a United States Army soldier and US government politician in pre-war editions.
As was traditional, the entire set was re-issued with the publication in 1863 of the 16th volume. The whole Cyclopædia was again re-issued in 1864.
Contributors
A notable contributor was Karl Marx, then a European correspondent for the New York Tribune, who, appeared as the writer, while most of those articles were written by Friedrich Engels, especially the articles on military affairs, which belonged in Engels' domain in the division of labor between the two friends. Because of his deep knowledge of all things military, Engels had earned the nickname "General". Marx wrote a highly unsympathetic biographical article on Simon Bolivar.

Why this record matters
The phrase “encyclopedia created and published by D. Appleton & Company” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Chronology, provenance and viewpoint should be read together before a broad social or political interpretation is accepted. The source revision retrieved here is dated Sep 3, 2026. The linked authority identifier is Q11084139. 1 of 2 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank. The first chronological checks are 1858, 1863, 1873 and 1864.
Official terminology may obscure informal participation, dissent or communities documented only indirectly. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
