The library bureaucracy insisted that all official documents be signed

in black ink.  Oscar Berg assiduously enforced the black-only rule

among his several subordinates.  There was the widespread perception in

the library central administration, right or wrong, that black was

simply the more professional ink color.   Oscar buried himself in

his office one hour every Friday afternoon to review his

branch’s official documents to ensure adherence to the library’s black

ink protocol.    Oscar knew that the supervising authorities at the

central administration would detect any deviation from the library’s policies.

Oscar needed to protect himself from censure by the authorities.
