The Open House will be held from 2 to 4 p.m. and is sponsored by the Friends of the Greenburgh Public Library.
Beth and Scott Bierko will perform a concert for children of all ages. Mary will be honored right before the concert and afterwards.
"Mary has told stories to generations of Greenburgh's children," the library said in a statement. "Her creativity, passion, and enthusiasm for children's literature and libraries is inspiring."
