History
The Plains branch opened on January 20, 1991. It was the first branch in the ACPL system to be built specifically for library service. It heralded in a new era of library building projects; locations had previously been rented spaces or converted storefronts. Encouraged by the continuing growth of The Plains community, the library doubled in size during a quarter-million dollar expansion project in 1999. The branch's central location in the county makes it a popular spot for residents from neighboring communities.
