Emergency Modified Opening Hours

Effective Wednesday June 18^th, the Library will be open to the public at 9 AM and will close at noon.  The Library will be closed as scheduled on Friday July 4th and Saturday July 5^th, due to the Holiday weekend.  We will open for the remaining Saturdays in July, 9 AM to noon, to accommodate as many patrons as possible, until necessary construction is complete.

The Borough of Mountainside is currently replacing the main HVAC system, original to the Library building.  Work began on May 19^th, and is projected to last well into the middle of July.  As a result the building has no cooling or proper ventilation, such that air quality and temperature in the building are no longer in compliance with Public Employee Occupational Safety and Health requirements.  The Library will continue to make every effort to deliver our usual high level of service, within these limited hours.

Unfortunately, Adult programs scheduled to take place during this period are cancelled.  Children’s Summer Reading programs will continue as scheduled and registrants will be contacted if there are any changes.

For updates and programming details, please call the library or go to our Newsletter page.

We look forward to a new efficient air conditioning system later this summer.
