OK, so if vinyl is warmed sufficiently and put under some pressure, it 
can be forced to change shape, which is how vinyl records are made in 
the press as we all know. Same for shellac, altho lower temps will warp 
shellac. I assume a record store at an angle or with something on top of 
and below could do the same over time, be forced out of a flat 
condition. If these transcription records were packed tightly in boxes, 
perhaps this will not have occurred.

That would explain why I have seen so little warping in my vinyl 
collection, excluding those records which came factory pre-warped.
