This volume supersedes the Third Edition's web based Index/Table of Authorities (Index/TOA), 2006. On August 6, 2010, the web versions of the Third Edition of the Principles of Federal Appropriations Law, Volumes I, II and III, were reposted to include updated active electronic links to GAO decisions. Additionally, the Third Edition's web based Index/TOA was replaced by an Index/TOA that incorporated information from Volume I, II and III. These four documents can be used independently or interactively. To use the documents interactively, click on http: //www.gao.gov/special.pubs/redbook1.html and you will be directed to brief instructions regarding interactive use. The Security of this file is set to prevent a situation where linked references are appended to the PDF. If this change prevents an Acrobat function you need (e.g., to extract pages), use the the password "redbook" to revise the document security and enable the additional functions.
