Libraries have been a part of Carver County history since the county was started. The earliest library began in 1858, and many more followed. In the twenty-first century, there are five full libraries and three express library branches. Total circulation is over one million books per year and rising.
County resident O.D. Sell founded the Carver County Historical Society (CCHS) in 1940. The original task was to collect and preserve the history of Carver County and Minnesota. He had a large personal collection of objects relating to the county's history that he wanted to share with the public. This forms the core of the CCHS collection.
The Carver County Fair has a long and rich history, dating back to 1868. On July 20, the Carver County Agricultural Society formed in Chaska. Later that year, on October 10, this group held the first Carver County fair in Chaska, to display their crops and animals. An elected Board of Directors planned the fair. Despite later battles over location, the fair has been held almost every year since.
