Hanover is accepting nomination papers for the annual town election on May 10. The terms of two selectmen — John Barry and Susan Setterland — will expire this spring. There will also be races for two School Committee seats, three positions on the Housing Authority, two members of the Board of Assessors, and one member on each of the following: the Planning Board, the Board of Health, and the Board of Public Works. The town will also elect a library trustee and a town moderator. Candidates must collect 50 signatures from registered Hanover voters and turn them into the registrar's office by March 24 to be eligible to run.
