Library and Information work is not just about being able to
provide information.
Neither is it just about how to use book content pages,
indices, or being able to update loose leaf binder files.
It is also about being able to interpret some of the
following:
– Telephone area codes.
– Post Office sort Codes, or Zip codes.
– Dewey Classification numbers.
&
– ISBN & ISSN Numbers.
Of course there are a lot of other codes or information
systems which one may be asked about during the course of
a typical Library working day.
