The Sciences Library, nicknamed the "SciLi" (pronounced “sigh-lie”), at Brown University is a high-rise building in Providence, Rhode Island built in 1971 in the Brutalist style.

Clashing with late 19th century and early 20th century colonial revival houses and abutting street-level shopping on Thayer Street, the Sciences Library is often seen as an imposing and obtrusive addition to College Hill by critics who supported the 2016 demolition of the Fogarty Building, one of Rhode Island's few examples of brutalist architecture.

Proponents of brutalism assert that it is the world's most endangered architectural style[4] and, given the loss of dozens of significant brutalist buildings in the US in the twenty-first century, the Sciences Library is a rare surviving example.

[6] In 2006, the first and second floors and the basement of the Sciences Library underwent extensive renovations and were transformed into the Susan P. and Richard A. Friedman Study Center.

The Center houses academic mentoring and support programs and serves as the campus clearinghouse for information about research and fellowship opportunities at Brown and around the world.
