The Seattle Public Library (SPL) is the public library system serving the city of Seattle, Washington. Efforts to start a Seattle library had commenced as early as 1868, with the system eventually being established by the city in 1890. The system currently comprises 27 branches, most of which are named after the neighborhoods in which they are located. The Seattle Public Library also includes Mobile Services and the Central Library, which was designed by Rem Koolhaas and opened in 2004. The Seattle Public Library also founded the Washington Talking Book & Braille Library (WTBBL), which it administered until July 2008. All but one of Seattle's early purpose-built libraries were Carnegie libraries. Although the central Carnegie library has since been replaced twice, all the purpose-built branches from the early 20th century survive; however, some have undergone significant alterations. Ballard's former Carnegie library has since housed a number of restaurants and antique stores among other enterprises, while others such as the Fremont and Green Lake branches have been modernized and remain in use as libraries.

The Seattle Central Library is the flagship library of the Seattle Public Library system. The 11-story (185 feet or 56.9 meters high) glass and steel building in downtown Seattle, Washington was opened to the public on May 23, 2004. Rem Koolhaas and Joshua Prince-Ramus of OMA/LMN were the principal architects, and Magnusson Klemencic Associates was the structural engineer with Arup. Arup also provided mechanical, electrical, and plumbing engineering, as well as fire/life safety, security, IT and communications, and audio visual consulting. Hoffman Construction Company of Portland, Oregon, was the general contractor. The 362,987 square feet (33,722.6 m2) public library has the capacity to hold about one and a half million books and other materials. It offers underground public parking for 143 vehicles and over 400 computers accessible to the public. Over two million people visited the library during its first year. It is the third Seattle Central Library building to be located on the same site at 1000 Fourth Avenue, the block bounded by Fourth and Fifth Avenues and Madison and Spring Streets. The library has a unique, striking appearance, consisting of several discrete "floating platforms" seemingly wrapped in a large steel net around glass skin. Architectural tours of the building began in June 2004. In 2007, the building was voted #108 on the American Institute of Architects' list of Americans' 150 favorite structures in the U.S. It was one of two places in Seattle to be included on the list of 150 structures, the other being T-Mobile Park.

The Federal Reserve Bank Building, also known as the Federal Reserve Bank of San Francisco, Seattle Branch, served as the offices of the Seattle branch of the Federal Reserve Bank of San Francisco for over 50 years, from 1951 to 2008.

After ownership of the Federal Reserve Bank Building was transferred to the General Services Administration in 2013, it was auctioned to Martin Selig Real Estate in 2015 for $16 million; the firm later announced plans to build a 48-story mixed-use skyscraper atop the existing building, but scaled back the project to only seven floors. The addition was completed in 2020. The building has been listed on the National Register of Historic Places since 2013.
