Volume IV: Compiled and revised by Silas Felton. 1063 pp., revised with books missed in vols. I,II, and III, regimental publications, personal narratives, biographies, campaigns and battles, Northern and Southern. Felton?s new compilation is without peer. He covers the subject from five different perspectives: Regimental Publications and Personal Narratives, Union and Confederate Biographies, General References, Armed Forces and Campaigns and Battles.And, making the work extremely useful, the last 236 pages contain a complete Index of Authors of Volumes I through IV as well as a new Index of Titles in the Revised Volume IV.Furthermore, to clear up confusion created by the multiple names often used by Confederate units during the war ? artillery batteries in particular ? which carried a state designation but were commonly known by the battery commander?s name, Felton has cited a written work with a single number designation but indexed and listed it under its common appellation to aid the researcher and eliminate confusion.

Review: "The editors have compiled a comprehensive source that provides a first-stop reference on broad areas or specific topics on the Civil War. The contemporary photographs and lithographs bring the human element into the encyclopedia, a type of reference known more for facts and figures than emotions. The primary-source-documents volume brings obscure resources together, which will further illumine the period for students."--"Outstanding Reference Sources," American Libraries, May 2001

Some vols. include supplemental journals of "such proceedings of the sessions, as, during the time they were depending, were ordered to be kept secret, and respecting which the injunction of secrecy was afterwards taken off by the order of the House."
