Telephone / Zip Code Directories

General Comments

Telephone directories facilitate community access to telephone listings for selected cities in the U.S. This saves patrons the expense of directory assistance charges and often provides better service than is available from directory assistance (e.g., the subject access of the yellow pages listings, the ability to browse a particular surname). Online zip code directories allow patrons quick access to current zip codes throughout the U.S.

Development Plan

The library does not purchase paper directories since they are provided free of charge by the phone company. This collection provides a paper copy of all Wyoming directories and a limited number of directories for major cities surrounding the area.

Influencing Factors

  • electronic/Internet sources availability.
  • availability of free directories.
  • present and potential relevance to the community.


  • All paper editions are discarded as newer editions are received.
