Springfield-Greene County Library District (SGCL) is a library system that operates in both Springfield, Missouri and Greene County, Missouri. Springfield and Greene County Libraries operated as separate entities until 1961, when the Greene County Library board began contracting services from the Springfield Public Library. Boards from both the Springfield Public Library and the Greene County Library decided that it would be more effective to operate as one entity and merged in 1971 becoming the Springfield-Greene County Library District.
