7 library museum-pass programs, verified on the libraries' own pages. A public-library card — free for residents — reserves real museum admission in every metro below. Each program page covers who qualifies, how booking works, the marquee museums on the pass, and where "free" is actually a discount. Pair a pass with the same city's free-day calendar and most of a museum trip stops costing money.
