Библиотечная система округа Кинг: Обзор и достижения

The King County Library System (KCLS) is a library system serving most residents of King County, Washington, United States. Headquartered in Issaquah, Washington, KCLS was the busiest library system in the United States as of 2010, circulating 22.4 million items. It consists of 50 libraries, a Traveling Library Center, a mobile TechLab, and the ABC Express children’s library van. KCLS offers a collection of more than 4.1 million items, including books, periodicals, newspapers, audio and videotapes, films, CDs, DVDs and extensive online resources. All KCLS libraries offer free Wi Fi connections. Patrons can check out 100 items at once and hold up to 50 items.

The library system began in 1942 when voters in King County established the King County Rural Library District in order to provide library services to people in rural areas with no easy access to city libraries. Funding for the library system is provided from property taxes. Funding measures for the system passed in 1966, 1977, 1980, 1988, 2002, 2004, and 2010. Property taxes account for 94% of revenue today. The KCLS budget for 2017 was $120 million. The system received a $172 million capital bond in 2004 to rebuild, renovate, and expand most of its existing libraries, as well as building new libraries. KCLS extends access privileges to residents of its service area, which includes all unincorporated areas of King County as well as residents of every city in the county except Hunts Point and Yarrow Point, which do not offer any library service at all. Residents of Seattle – which maintains its own library system – are allowed access to KCLS collections under reciprocal borrowing agreements between KCLS and Seattle's libraries. KCLS also extends reciprocal borrowing privileges to residents of many other library systems in Western and North Central Washington. KCLS annexed Renton's public library system in 2010 following a vote by the city's residents. In 2011, KCLS won the Gale/Library Journal "Library of the Year" award.

KCLS consists of 50 branches, the Traveling Library Center, ABC Express Vans, a mobile TechLab, and a service center located in Issaquah that houses the library's administrative offices. A program to build 17 new libraries and renovate or expand 26 other libraries was completed in 2019 with the opening of the Panther Lake Library in Kent.

In 2016, KCLS circulated 20.8 million items, the third most in the United States. KCLS is subscribed to OverDrive, an online service that offers digital e book, audiobook, and magazine checkouts for library patrons. In 2023, the library system had 8.8 million digital checkouts—the third most of any system in OverDrive worldwide.
