Included in the policies that every library should have are the board’s by-laws. These are the rules under which the board will operate. By-laws describe the board offices and the duty of each office, the rules under which regular and special meetings will be held, the standing committees of the board (if any) and any other permanent operating procedures for the board itself.

Below are links to examples of by-laws for cities and for districts.
