(2) Upon resolution, ordinance or election pursuant to ORS 357.417, the governing body may appoint a library board. The library board of a city, county or county service district, as determined by the governing body, shall consist of not less than five members nor more than 15 members. In the case of a school district or community college district, such board shall consist of five, seven or more members at the discretion of the governing body.

(3) If the board will consist of five members, one member shall initially hold office for one year, one for two years, one for three years and two for four years, from July 1 in the year of their appointment. If the board will consist of seven members, one member shall initially hold office for one year, two for two years, two for three years, and two for four years, from July 1 in the year of their appointment. If the board will consist of six members or more than seven members, the members first appointed shall hold office for such terms as will achieve the staggered term base established for smaller boards by this section. Succeeding appointees shall hold office for a term of four years from July 1 in the year of their appointment. At the expiration of the term of any member of such board, the governing body shall appoint a new member or may reappoint a member for a term of four years. If a vacancy occurs, the governing body shall appoint a new member for the unexpired term. No person shall hold appointment as a member for more than two full consecutive terms, but any person may be appointed again to the board after an interval of one year.
