Everyone here is bringing up valid points,but when I talked to Jim M. earlier this year,his biggest concern/frustration was to try & enforce GM facilities throughout to STOP throwing out the records they have left into the garbage.
It doesn't matter what they ultimately decide to do with them in the future,if all the remaining records are COMPLETELY gone by then.
Every day,somebody,somewhere in a GM Building is throwing out a Box filled with old paperwork.And No one over there really knows what's in them,or even Cares.
