After only six months, Flower Memorial Library in Watertown is once again looking for a new executive director. This comes following the sudden resignation of Margaret Waggoner late last week. The library says Waggoner resigned from the position and is no longer on the job. The sudden resignation came the same week the library board was undertaking a six month performance review of her. No additional details were made available. Reference librarian Yvonne Reff will be taking over on an interim basis, and she could be considered for the job on a full time basis as well.
