National Tribune articles are a key part of modern Civil War research. "The National Tribune was the premier Union veterans’ newspaper of the post-Civil War era. Launched in 1877 by a New York veteran to help his comrades and sway Congress to pass better pension laws, a short time later the National Tribune began publishing firsthand accounts penned by the veterans themselves, and did so for decades thereafter." SB typically concentrates on more commercial fare, but they have published reference works in the past. Here, they've teamed up with Richard Sauers to put out The National Tribune Civil War Index in three volumes currently scheduled for a late 2017 release.
● The National Tribune Civil War Index: A Guide to the Weekly Newspaper Dedicated to Civil War Veterans, 1877-1943. Volume 1: 1877-1903
● The National Tribune Civil War Index: A Guide to the Weekly Newspaper Dedicated to Civil War Veterans, 1877-1943. Volume 2: 1904-1943
● The National Tribune Civil War Index: A Guide to the Weekly Newspaper Dedicated to Civil War Veterans, 1877-1943. Volume 3: Author, Unit, and Subject Index
More from the description: "The first two volumes are organized by author, his unit, title, and page/column location. The third volume―the main index―includes a subject, author, and unit guide, as well as a “Unit as Sources” index that lists articles that mention specific commands but are written by soldiers who were not members of that unit. As an added bonus, this reference guide includes the contents of both the National Tribune Scrapbook and the National Tribune Repository, two short-lived publications that included articles by veterans, and a listing of the major libraries that have National Tribune holdings." Undoubtedly, research libraries of all kinds will want a copy of this set for their reference sections.
