The LaGrange Association Library was formed in 1982, when it received its provisional charter from the New York State Board of Regents. Prior to this the Town of LaGrange contracted with Adriance Memorial Library for services. The LaGrange Association Library began offering services in 1983, in the basement of the Town Hall with a collection comprised primarily of donated books.
By 1988, the Library had outgrown the Town Hall and was moved to the Freedom Executive Park. In 1990, the LaGrange Association Library became one of the first libraries to join the Mid-Hudson Library System Automated Network. Staff and volunteers saw that each item in the Library was barcoded and entered into a database. Library items began circulating online in June 1991. Circulation began to increase at a rapid rate and exceeded 100,000 in 1992.
The collection increased rapidly; in 1996, the Library expanded its space in the Freedom Executive Park. The Children’s Room became a room contiguous to the Library and an online public access catalog was made available to Library patrons.
The collection, patron demand for adult and youth programs, technology, and digital literacy needs continued to grow over the years. Programs for all ages became severely limited due to a very small program room which served multiple purposes. In 2016, the Library became a passport acceptance facility, necessitating additional space in which to conduct this convenient service for patrons.
The Library Board investigated several physical plants which could accommodate the growth in services and materials to the community for the long term. In November 2020, the Library relocated to its present leased space in the heart of Town Center at 1110 Route 55 in Lagrangeville, with the potential to nearly double its former square footage.
The Library Board continues its Capital Campaign to complete renovations for the total space which will include a dedicated youth program room, a toddler play area, a larger community room, a passport application office, and an expanded main library area with ample shelving to bring the balance of the collection out of storage.
