The Welfare Rules Databook provides tables containing key Temporary Assistance for Needy Families policies for each state as of July 1999, as well as tables describing selected policies from 1996 through 1999. The Databook is divided into five groups of tables: Initial Eligibility in 1999, Benefits in 1999, Requirements in 1999, Ongoing Eligibility in 1999, and Policies across Time 1996-1999. The tables are based on information in the Welfare Rules Database, a publicly available, fully searchable database available on the Assessing the New Federalism project's website.
