The Freeport Memorial Library was established in 1884 by Professor Loren M. Burdick, principal of the Freeport Schools, with funds raised by amateur entertainment. For a while, the books were kept in the clothes closet of the principal's office in the Grove Street School. In 1895, the Board of Regents of New York State granted a provisional charter. The following year 759 volumes constituted the Library's book collection and circulation reached 1,174. A permanent charter, signed by Melvil Dewey, was granted on December 21, 1899.

The Library was housed in the school until 1911 when it was moved to a rented room in the Miller Building on South Grove Street . Members paid ten cents for a card and were permitted to borrow two books, one fiction and one nonfiction. In 1920, the first public drive for funds for a new building was started. Elizabeth Pirodsky, a sixth grade student at the Seaman Avenue School, was the first donor. In August 1920, Theodore Roosevelt Jr., Assemblyman for the Second District and the late President's son, sent the Freeport Memorial Library Association a $20 donation. Assemblyman Roosevelt also issued a statement commending the choice made for a memorial and encouraged gifts from the American Legion members. One thousand citizens of the Village of Freeport voluntary contributed $36,500 to the fund drive. John Anderson, owner of the site of the new building at the corner of Merrick Road and Ocean Avenue, was paid for $14,775 for the land. Ground was broken for the Library on the northwest corner of Merrick Road and Ocean Avenue on April 30, 1921. The cornerstone was laid on June 25, 1922 . On Memorial Day in1924, the Beaux Arts building designed by architect Charles M. Hart was dedicated as the first war memorial library in New York State. In 1925 the Freeport Library, officially changed its name to the Freeport Memorial Library. Three years later, a memorial tablet with the names of Freeporters who died while serving in the military during the Civil War, Spanish American War, and World War I was dedicated. This table included the inscription: "In this Memorial / As in the hearts of the people of Freeport / The Memorial of the Men and Women who served in the / Wars of our Country will be enshrined forever."

The completion of the Freeport Memorial Library building was an appropriate climax to the efforts of the citizens of the village to find a suitable and lasting memorial to the sacrifices made by those who died in the service of their country. A close look at the engravings on the original building reveals the names of the historic battles of World War I, the Spanish American War, and Civil War.
