For me I don't see the necessity to have the sources.
But so may Dave say he doesn't see the necessity to credit Colin as his source! ;)
Well, if you don't see the necessity it's at least a sign of reverence to those who have researched before you.
Colin has done a great job, no doubt, but others have done before him and perhaps they wouldn't mind being credited either. ;)
What Dundonnel has asked for is completely reasonable and we are all in his debt. When it comes down to the basics, my only concern is WHO created the list and that speaks to its credibility. I do not know anyone having more integrity than someone who is extremely knowledgeable, someone we all trust as having done due diligence and someone who is open to change.
I would only suggest that you include your name (Dundonnel) to every catalog, and maybe the date last modified, and a possibly malibox or topic where viewers could send updates or corrections. Then replication is not an issue, but these are only suggestions and the list is fine as is..
Attributing each and every entry to a specific source could make it a musical Tower of Babel.
And what source would make sense for The 1812 Overture or Beethoven's 5th for that matter, and who would care?
I check it to see what I may have missed by a favorite and/or prolific composer but it is not the only place I look. This is an imperfect world and Dundonnel
has done us all a great service with his efforts.
Please continue the lists as is, they have been invaluable to me and I am grateful that they exist.
