Garland, New York, 1998
This huge two-volume set is simply a massive collection of tunes, all reduced to a single melody line, from all kinds of different sources, Irish, English and Scottish. It seems any tune with even the vaugest claim to Irishness is included. There are no details given about the individual tunes, just codes representing tune style, form, mode and source.
