well as a carriage house for Museum storage and display. The library, archival, and museum collections continued to grow, as did programming and staff, throughout the 1980s and 1990s; the Filson's name changed from “Club” to “Historical Society” as a focus on scholarly research on Ohio Valley history was introduced. Plans for expansion of the 3rd Street campus began in 2002 with the purchase of the Bank One building located at 4th and Ormsby, a 60,000 sq ft building with two parking lots. The Filson's major expansion began in the 2010s with renovations to the Ferguson Mansion and carriage house, and the construction of the Owsley Brown II History Center, creating space for exhibition galleries, expanded library and special collections reading rooms, programming and event rental venues. Collections The Filson Historical Society's Collection includes approximately 2.1 million documents, photos, & prints, 50,000 books, 10,000 museum items, and 400 portraits. The Filson began collecting historical material soon after its founding in 1884, when few other Kentucky institutions were doing so. With many of its early members belonging to Kentucky's oldest and most prominent families, the Filson was able to begin assembling an important collection of original letters, diaries, business records, and other primary sources. Its holdings for the late eighteenth through mid-nineteenth centuries are unrivaled in Kentucky. The collection focuses on Kentucky, the Ohio Valley, and the Upper South, but is national and even international in scope, with researchers from across the nation and abroad visiting each year. The Filson's unique holdings are essential primary sources for scholars of the Trans-Appalachian frontier; the Lewis & Clark Expedition; antebellum enslavement and emancipation; Southern Jewish history; regional architecture; Progressive-era urban reform; Suffrage and Women's Rights; regional theater, music and literature; river and rail transportation; and military history from the 18th to 20th centuries. In addition to manuscript and rare book holdings, the Filson holds an important museum collection of early Kentucky portraiture, Ohio Valley artists in a variety of media, and textiles and historical clothing. The Filson's website has extensive collections listings with finding aids, a keyword-searchable database of manuscript collections, digital collections of photographs and museum objects, and a library catalog of rare books and pamphlets. Ohio Valley History regularly publishes collections essays by Filson archivists and curators that discuss new acquisitions, themes running across collections, and raising awareness of marginalized voices from within the collection. Since 2001, the Filson has supported
