The Talking Machine Forum — For All Antique Phonographs & Recordings

I've been trying to find recording dates for some of my DDs; and the spreadsheets I've found so far are woefully incomplete, stopping at matrix #9018. Furthermore, I need to identify some titles and artists on discs with missing labels: they are almost invariably not listed there.

Is there a site that has a comprehensive listing of DDs? (or at least the 50000 series up to 1927?)
