This is kinda cool too (additional public domain songbooks). Maybe just for the real nerds here: https://mudcat.org/child/download/OtherSongBooks. I'll be working to organize, label, and index (make searchable) these additional public domain song books over the next few weeks.

I'm also working on a reasonable mobile interface for mudcat. So, all the long overdue features are finally coming 'round...

In my defense, you fuckers don't exactly like (appreciate) change, so... let's just say I haven't had the incentive...

But you do certainly deserve it...
