The Butler Public Library, 218 N. McKean St., will close Thursday and Friday while work on its entry ways is completed.
The library will reopen at 8 a.m. Saturday.
That work is part of a $400,000 overall exterior renovation,
Renovations include having its existing covered porch converted into a sunroom, the addition of a courtyard/outdoor amphitheater, new sidewalks and curbs, improved fencing and an expanded entrance, with new lighting and seating.
The project is scheduled to be done by the end of the year.
