|The original Filson Club building (JF-CN-99) meets National Register Criterion A, as it is associated with events that have made a significant contribution to the broad patterns of our history. The Filson building is emblematic of the rise of private historical societies that emerged outside of the bounds of traditional institutional repositories of historical materials, such as libraries, colleges and universities, and government records departments. The building's significance is evaluated within the context Private Historical Societies and Libraries in Louisville, Kentucky, 1865-1965. Part of its significance is realized in its design. The club could have chosen modem-era design aesthetics for the new facade placed on the front to unite the 2 historic buildings. The Club members' choice to use historic revival styles, rather than modem design, surely relates to the related interest of the Club to celebrate local history.
