The FEC also publishes reports filed by Senate, House of Representatives and presidential campaigns that list how much each campaign has raised and spent, and a list of all donors over $200, along with each donor's home address, employer and job title. This database also goes back to 1980. Private organizations are legally prohibited from using these data to solicit new individual donors (and the FEC authorizes campaigns to include a limited number of "dummy" names as a measure to prevent this), but may use this information to solicit political action committees. The FEC also maintains an active program of public education, directed primarily to explaining the law to the candidates, their campaigns, political parties and other political committees that it regulates.
