This is an index of all the old-time tune books I have scanned and indexed so far. I do this so that I can import the book into forScore, the sheet music management app for iOS. (It’ll do just fine with plain PDFs, but I wrote a tool to add the metadata automatically, rather than having to type it in painfully on the iPad keyboard for each tune.) I have some other valuable printed resources that I haven’t scanned or indexed yet, mainly because of their size: Dear Old Illinois and the Milliner-Koken collection are huge. I will probably never have the M-K book in forScore, alas, unless they start selling a PDF version of it.
