The building was of brick, with arched windows and large heavy wooden doors at the entrance.

The new library opened on March 25, 2007 and added many new or enhanced services, including over 50 public internet terminals, the 205-seat Camille Budarz Theater, an art gallery, and Westchester County's first radio frequency (RFID) circulation system.

1,000 visitors attended on the opening day, which include guided tours and a piano performance by Ossining resident Camille Antoinette Budarz.

Other celebratory events, including a film series, library history lecture, ice cream social, and genealogy program, were scheduled as part of the celebration.

The new library has features that allude to historic Ossining architecture, and uses natural stone and brick, materials of the Hudson Valley.

[6][5][7] The lower level has a cafe, art gallery, and theater; the first floor has the circulation desk, media section, multicultural collection, and children's room.

[10] Given Ossining's large Hispanic population, the library has services including a weekly English Conversation Group, English as a Second Language classes twice weekly, a Spanish film series, a multicultural collection, and performances and celebrations during National Hispanic Heritage Month.

[5] The library's collections include several non-traditional circulating items: nature observation kits, cake pans, fishing poles, and Wii games.

[11] The library also offers free admission to local and regional museums and nature centers.
