CAGW is the source for information about pork-barrel spending.  Since 1991, the annual Congressional Pig Book has provided the authoritative list of pork in the federal budget.  A "pork" project is a line-item in an appropriations or authorization bill that designates funds for a specific purpose in circumvention of established budgetary procedures.  To qualify as pork, a project must meet one of seven criteria that were developed in 1991 by CAGW and the Congresional Porkbusters Coalition.
