Louisiana Public Document Depository ProgramLouisiana government agencies publish many documents that are of interest to the general public. Louisiana law requires that state agencies submit copies of their publications to the Recorder of Documents, located within the State Library, for distribution to depository libraries throughout the state via the Louisiana Public Document Depository Program (PDDP). Libraries participating in the distribution program include Louisiana academic, public, and special libraries and the Library of Congress in Washington, D.C.
