For the second day in a row, the Oak Bluffs Library has been closed due to a malfunctioning air conditioning system.

The library was closed at 11:30 a.m. today. On Thursday morning library officials first announced the early closure of the upstairs portion of the library. Soon after, the rest of the library was closed. The library meeting room, where a book sale is ongoing, is fully air conditioned and remains open.

The building has a longstanding history of heating and air conditioning problems.

Library director Sondra Murphy said she can not yet anticipate if the library will reopen tomorrow, But if temperatures remain near 90 degrees, as they have for much of the week, the library may be forced to again shut its doors.
