The 12-volume Universal Cyclopaedia was edited by Charles Kendall Adams, and was published by D. Appleton & Company in 1900.
The original Editors in Chief were Frederick Augustus Porter Barnard and Arnold Henry Guyot[1] From 1893–1897, it was republished as Johnson's Universal Encyclopedia.
As Johnson was no longer involved, this edition was published as Universal Cyclopaedia, which is described as one of the best encyclopedias of the time.
[3] In the "Publisher's Announcement" in Volume I of the original edition, A. J. Johnson stated that Horace Greeley suggested the plan for the work and urged its publication, and was a primary advisor.
One of Greeley's requirements was that the cyclopaedia "be pre-eminently a book of facts, and to a very limited extent, if at all, a volume of discussions or of critical opinions.
