A few sheets are missing from the archive, although we think we know what's on them:
MM36ii, MM102a and MM195
and in some cases we have only a rather poor-quality copy of the original:
MM4*, MM5*, MM13*, MM21*, MM22*, MM23*, MM26*, MM28*, MM30*, MM32*, MM33*, MM34*, MM40*, MM43*, MM82*, MM100*, MM149*, MM149a, MM165* and MM169*
although the starred ones have since been typeset instead.
So, if you have a copy of a missing sheet or a higher-quality version of one then we'd be very grateful if you could lend it to us, or send us a scan, so we can add it to the archive. If you'd like to help with the typesetting then please see some suggestions of which sheets to choose.
Go to the tunes listed by title or by sheet.
