September was first designated as Library Card Sign-Up month in 1988, but was first observed the previous year.

September is Library Card Sign-Up Month - a time when the American Library Association and libraries across the country remind parents that the most important school supply of all is @ your library® - it's your library card. September was first so designated in 1988, as a continuation of a national campaign launched the previous year.
