Bill May of Butler will present “Civil War Photographs in 3-D — Part II” at 7 p.m. Wednesday in the Butler YWCA, 120 W. Cunningham St.

The program is free and open to the public and sponsored by the Butler County Civil War Roundtable.

During the Civil War, 90 percent of all photographs were shot as stereo images.

When viewed with a 19th century stereo viewer, these images were brought to life with a 3-D effect.

May has used modern computer technology so that these images are able to be viewed on a large projection screen in 3-D format.

The Butler Public Library, 218 N. McKean St., will host a holiday reception for its donors Thursday evening.Because of that, the library will close to the public at 4:30 p.m. Thursday.
