PHOENIX — Phoenix residents with overdue library books might want to wait a bit before bringing back their borrowed copies of the current best sellers.

Starting in November, Phoenix’s public library system will join a growing number of libraries around the United States that have dropped overdue book fees.

A unanimous City Council decision this week makes Phoenix, the fifth-largest metropolis in the U.S., also the largest one nationwide to dump the fines. Public libraries in the more populated cities of New York, Los Angeles, Houston and Chicago still charge them.

“We know that for some residents, the prospect of a late fee can act as a deterrence to using library services in the first place,” Phoenix Mayor Kate Gallego said after the vote.

Phoenix City Librarian Rita Hamilton said the move would allow the system comprised of 17 libraries to ensure “that access to our resources is as equitable as possible.”

The Phoenix system has been charging 20 cents per item per day, which can add up quickly into dollars owed, an extra expense some families cannot afford. Other libraries around the nation charge 25 to 35 cents per item per day.

Phoenix’s move is part of a new worldwide trend by libraries to eliminate fines the American Library Association considers “a form of social inequality.”

At its January meeting, the association encouraged libraries to consider dropping the fees, saying they “present an economic barrier to access of library materials and services.”

Baltimore’s Enoch Pratt Free Library last year eliminated fines on overdue books and other materials. The Salt Lake City Public Library System stopped charging the fees July 2017.

That same year, libraries in Columbus, Ohio and Nashville, Tennessee, dropped them. The library in Broomfield, Colorado, went fine-free Jan. 1, and Oakland, California, public libraries followed suit in July.
