Another member of the Autauga-Prattville library board resigned Wednesday, according to library director Andrew Foster.

The board has been embroiled in controversy regarding book challenges for months. Three members resigned Monday after the Autauga County Commission appointed Doug Darr to the board last week without seeking consultation from the current board, which is the usual procedure.

Tommy Gamper resigned today and had been on the board since 2014. Chair Susan Poteat, vice-chair Wayne Lambert, and Pam Frederick left Monday. Another board member left in October for an unrelated reason. With Darr and another recent appointment, this week’s resignations leaves five spots to fill on the seven-member board.

The commission was supposed to fill vacant seats using board recommendations during a Dec. 10 commission meeting. Foster said he and the board were unaware the commission was planning to appoint someone until the day of the meeting.
