Coming soon! The library's 1908 volume of Architectural Record has gone missing, so I've requested a copy of the article from another library.
Use Lexis Nexis News to search for articles in the Dayton Daily News. These will be text-only (unfortunately)
I've put a couple of books with information about Westcott House on reserve. They are:
Frank Lloyd Wright Monograph 1907-1913 (p 38-41): includes plans, elevations, sections, photos
Frank Lloyd Wright to 1910 (brief mention on p185): not too much info, but puts the house in context with other works at the time
