when does collecting become hoarding.
Most collectors publish their material,singers and musicians then benefit,most collectors look after their sources in one way or another.
I myself have published two tutors[with my own arrangements for song accompaniment]all traditional material or my own compositions.
I collected some tunes from an old fiddle player [who became afriend],none of thse tunes do I intend to publish,but have used to understand local fiddle technique and listened to for my own pleasure,and yes I looked after my source ,on one occassion I found him alone in his cottage [he hadnt eaten for two days]so I got his shopPing, lit a fire for him etc.
the problem with todays society is the looking after no 1 syndrome,Every collector has a moral duty to look after their sources.
