Facilities has been contacted regarding the burning smell in the Library. Initial reports indicate one or more belts in the exhaust system have broken causing the smell of burning rubber. HVAC people are on the way to check all the belts. I will update as I know more.
The problem is in one of the heat/air units and they have this unit shut down to make repairs. If you notice it get warmer in the building it is due to this unit being shut down. Hopefully repairs will not take long.
