Before going on disability leave in 2012, Ms. Koopman was a librarian at the Scott Memorial Library at Thomas Jefferson University in Philadelphia, where she held posts related to electronic services and digital collections. She began working there in 1995.
She did some of the first intellectual work on how to create an institutional library encompassing digital materials and wrote about it, said her husband, Eric Pumroy. In one such article in 2007, she wondered, "If we build it, will they come?"
"Whether intended for faculty papers, original journals, dissertations, or special collections, one of the challenges of building an institutional repository is recruiting appropriate content," she wrote. She then gave pointers based on her experience at Jefferson.
In addition to her career and civic pursuits, Ms. Koopman was an avid cultivator of African violets. She was active in the Burlington County and Springfield (Delaware County) African violet organizations.
Born in Des Moines, Iowa, and raised in Appleton, Wis., Ms. Koopman was a 1974 graduate of Lawrence University in Appleton. She earned a master's degree from the Graduate Library School at the University of Chicago in 1981. She worked as a science and engineering librarian at Indiana University-Purdue University Indianapolis from 1988 to 1995.
While there, she was active in the Indiana League of Women Voters and was president of the Indiana Pro-Choice Action League.
In addition to her husband, she is survived by daughters Rachel and Ruth Anne; and her father, John Koopman.
A memorial will be held from 2 to 4 p.m. Saturday, Jan. 18, at the Wyndham Alumnae House at Bryn Mawr College, 235 N. Merion Ave., Bryn Mawr. Interment will be private.
