I have a paper bias...so I keep at the moment...I catalogue as best as
I can and have that online (
www.collection.archivist.info search for
IM or IS to get instruction manual or instruction and service for
example), I then respond and scan if needed.
That includes the confidential as only the title is listed so nothing
is public, but at least a desperate person can find a copy via google
and we can talk :)
What to keep and what to throw the difficult question, unless you know
there is another out there, you may have the only copy, this is where
I put the archivist hat on and say keep or make steps to give to a
safe haven.
