With legal employers looking for cost-efficiency in their new employees, an official government website with free documents in PDF is one you'll want to bookmark and remember.
FDsys, the U.S. Government Printing Office's Federal Digital System, provides easy access to Congressional bills, hearings, and reports, the U.S. Code, the Federal Register and the Code of Federal Regulations, as well as Presidential documents and other materials. Some of the materials on FDsys are not available on HeinOnline, and all of them are accessible to anyone with internet access. Be sure to note the date coverage for each of the resources, which varies.
