The first reference of a library appeared in The Alamosa Journal on March 20, 1902 announcing that the Town of Alamosa donated a room above the fire station to the Library Association, which at the time was supported by membership fees and quarterly dues. Members of the Current Events Club and other town women volunteered their services as librarians, keeping the reading room open every afternoon and every evening, except Sunday.
