A district library commission shall annually, from its members, elect a president, secretary and treasurer. The secretary and treasurer may be one and the same person. The district library commission shall meet at least quarterly in each year. Failure to hold 4 formal meetings shall, at the option of the county library advisory board, necessitate the appointment of a new district library commission as provided in § 7102 of this title. The district library commission may adopt a rule that the failure of any member to attend a specified number of meetings of the district library commission shall create a vacancy in the office of such member.
