Gypsy, tell us more about your copy of Bronson. How much can I expect to pay? I checked Books on Demand and found only two volumes, Ballads 1 to 53 for $153, and 54 to 113 for $181.40.
Looks like this would be another good project for Loomis House, depending on what price they can come up with. I'd expect to get the whole set for $150 or less in a paperback reprint, but maybe that's expecting too much. Same with the Child set - $150 is outrageous, but I guess I'd pay it.
