you may not be able to trust the cleaners ... but i thot clean desks were for the security officers that came around late at night checking to see if you had complied with all clbuttified information being under lock. since they had to leaf thru all the paper that had been left out ... their job was much faster if there was nothing left out.

for clbuttified trash there were 50gal barrels, top lid was secured with padlock and had specially constructed slot. I don't think they were directly emptied, instead they were periodically collected with empty barrel replacing the collected barrel.

we had "internal use only" ... which was ok to leave out, the printed corporate telephone book was "internal use only". then was simple corporate confidential, which had to be kept under locked up at night. I once accidentially carried a document labeled corporate confidential into a gov. facility. the marine guards caught it on the search leaving and maintained that they had no way of knowing whether it was a gov. confidential document or a corporate confidential document (the corporate name possibly being just a gov. confidential clbuttification term). It took quite a while to get the document liberated.

then there was "confidential - restricted" ... basically need to know only. in the 70s, internal copies of the cern report to share comparing cms and tso got stamped "confidential - restricted" ... there was an objective of restricting employee knowledge about how bad tso was compared to cms.

the highest level were the candy striped "registered confidential" documents ... each page was embossed with large faint document serial number in the background (numbers were couple inches in size), aka there was a document publication number ... but in addition each copy of the document had a unique document serial number. these had to be kept in special double-locked cabinets. you had to sign for each serial numbered document and there were sporadic security audits where you had to show that each document signed out to you was still in your possession (and kept under lock and key). at one point I had a cabinet full of 811 documents, which was code name (taken from nov. 1978 inception) for 370-xa, 31bit virtual addressing, some of the stuff that showed in in 3081 processors.

misc. past posts mentioning "confidential - restricted" and-or "registered confidential"
