Documents Basics

The FDLP: Helping to Keep America Informed

The Federal Depository Library Program (FDLP) was established by Congress to ensure that the American public has access to its Government's information. Since 1813, depository libraries have safeguarded the public's right to know by collecting, organizing, maintaining, preserving, and assisting users with information from the Federal Government. The FDLP provides Government information at no cost to designated depository libraries throughout the country and territories. These depository libraries, in turn, provide local, no-fee access to Government information in an impartial environment with professional assistance.

SuDoc Explained

The government documents received at TCCL are housed in the Research Center at the Central Library (4th St & Denver Ave). These materials are primarily arranged by SuDoc, short for the Superintendent of Documents call number system.

The SuDoc system is an alphanumeric call number scheme that places materials together in the shelves according to the agency that issued the document, reflecting the organization of the government. Here's an example:
