Anti-Saloon League Museum
"From 1893 to 1933, the Anti-Saloon League was a major force in American politics. Influencing the United States through the printed word and lobbying, it turned a moral crusade into a Constitutional amendment. The League left a legacy of printed material at a site bequeathed to the Westerville Public Library which houses the Anti-Saloon League Museum. The Westerville Public Library, in an effort to preserve and share the League's story, has established this web site with financial help from a grant provided by the State Library of Ohio."

Through this process, I wanted to share it with all true history buffs out there, whether experienced or novice. Nothing more, nothing less! "
