"Personally, the collectors I respect are those who choose their subjects carefully and record everything they have to offer, especially the information that puts the songs into context."
I beg to differ. Vehemently. Randolph, probably the collector I'm most impressed with, recorded everything he encountered, and sorted it oiut afterwards. I think it's arrogant (and not to bright) to assume that you know, at the moment you're collecting something, whether you'll find it valuable in a year or so.
