I used them in 1994 to locate the "Best Little Whorehouse in Texas Goes Public" CD and not only did they have it, the guy on the phone had seen the show and was able to tell me about it!
(he didn't think it was as bad as the critics had made it out to be, but agreed that having prostitutes in lucite boxes with their legs spread while overweight men danced in front of them with their pants at their ankles might have been going a bit far!)
Great Resource!
