Renovations and modifications have not altered the original physical arrangement of the building, which comprises three separate facilities — a library, music hall, and athletic club — under one roof.

Despite the closing of the Homestead Steel Works two years earlier and the precipitous decline in employment and tax revenue, the library remained open and operational with grants secured by community volunteers and the investment income from Carnegie's endowment.

When the financial crash of 2008 reduced the endowment's value by $300,000, the library board furloughed its executive employees and assumed management responsibilities rather than cut services.

Fundraising efforts, revenue from athletic club memberships, music hall rentals, and concession sales have maintained the library's viability.

New locker rooms and classrooms were added to the lower level; an elevator was installed in the music hall and a welcome center in the gymnasium.
