The Mid-Columbia Prosser Branch has computers and free wi-fi available to the public. Completely remodeled in May 2015, the branch offers custom air-balloon art pieces, a meeting room, an expanded collection, and an impressive historical photo mural display.
Interested in becoming more involved in your library? Volunteers are welcome to apply at any time. You can also participate as a member of The Prosser Friends of the Library, which supports library programs and services through the sale of used books located in the library lobby. Please contact the library if you are interested in becoming a Friend or donating items, or email email@example.com; the Board meets here on the third Friday of every month at 1 pm.
The City of Prosser Library building was built in 1973, and Benton County residents were served by a Bookmobile and then a branch also located in Prosser. In 2001, the city contracted with the county library system to combine services as the Mid-Columbia Libraries' Prosser Branch.
Prosser Heritage Collection is now online. This project, showcasing historical photos from the Prosser area, was supported by a grant from the Washington State Library and assistance provided by the Benton County Historical Museum.
