If you're a user of GPO Access, you will need to shift to GPO's Federal Digital System (FDsys) by the end of 2010, as GPO plans to sunset GPO Access at that time. FDsys will then become GPO's sole electronic system of record. According to GPO, less than 1% of the content from GPO Access remains to be processed and added to FDsys. Otherwise, the data migration process for all 40 of its content collections is complete.
For more information on how to use FDsys, including both its search and browse capabilities as well as the types of collections it includes, select the "Help" link to the right of FDsys' main search box. In addition, a PDF copy of the 97-page FDsys User Manual is available at http://www.gpo.gov/help/fdsys_user_manual.pdf.
