The Library will be closed Sunday, 2/15/26, and Monday, 2/16/26, in honor of Presidents’ Day.

Spring 2026 Social Work Intern Katrina, our Social Work Intern from Stony Brook University, will be available on certain days.  Her schedule is usually: Thursday evening from 4-8pm and  Friday morning from 9am-12pm, excluding holidays.  Katrina will be with us from January to May 2026. She is here to assist with guidance on certain topics, help with decision making, and offer personal and confidential resources and referrals to those who need it. Those seeking talk therapy may ask for a referral, as Katrina is not able to provide counseling during her internship here at the library. To contact Katrina directly for her hours or appointments, please call or text: 631-388-6236
