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.
