[Callers] Do you share - or don't you?

[Hanny Budnick]

I wrote two emails to the person who definitely knew a dance (the caller)
asking the relevant questions about author, correct name and choreography. When 
no answer came, I turned to this list, successfully.
Now I wonder about folks' attitude about sharing the materials they carry in 
their collection, and about which they are being asked. Once a dance has been 
presented on a public dance floor, do you elect NOT to share? And what might be 
your reasons?
