GPO's Federal Digital System (FDsys) is an advanced digital system that will enable GPO to manage Government information in a digital form. FDsys will enable GPO to manage information from all three branches of the U.S. Government.

As a state-of-the-art digital content management system, FDsys will contain information gathered through three methods:

•   Files submitted by Congress and Federal agencies;
•   Information gathered from Federal agencies' web sites (often referred to as "harvesting" information);
•   Digital files created by scanning previously printed publications.

Some of the main functions of the system include:

Publishing
The U.S. Congress and Federal agencies will be able to submit files and orders electronically to GPO for printing and publishing services, electronic distribution, and inclusion in the Federal Depository Library Program (FDLP)

Searching for information
Government information will reach a wider audience by providing authentic; published Government information to the public through an internet based system

Preserving information
The preservation function of FDsys will ensure public access to government information even as technology changes

Version control
Multiple versions of published information are common; FDsys will provide version control for government information.
