The first library in Las Cruces was a collection of 500 books that the Women’s Improvement Association (WIA) kept at various member’s homes and then in a small office they had on Water Street. In 1927, thirty-three years after the WIA was founded, when the WIA Club House was built, the books were moved there. Members took turns to act as librarian.
One of the WIA members was Alice Branigan, who, along with her husband, Captain Thomas Branigan, was active in the community. When Alice died in 1932, she left her estate to various civic organizations, and bequeathed - for those days - a considerable sum of money to the town of Las Cruces for a public library to be named in honor of her late husband.
