This book addresses the various forums in which the researcher may be immersed, from the legislative history of a statute to determining how to ask the government for documents not yet made available to the public. Along the way, the authors discuss the various types of tax-related court opinions, government documents, and law review and journal articles. Considerable attention is given to both the authoritative weight of each document and how it can be found. Research in the international tax area, a complex and dynamic area of tax, is discussed in great detail. Finally, the authors provide strategies for organizing the information into a written document, whether it is a response to an information document request or a brief to be filed in Tax Court. Throughout the pages of Federal Tax Research, examples of real-life situations, practice notes, research tips, and snippets of actual court opinions add breadth and life to the technical information. These illustrations of the practical application of the rules allow the researcher to become a more effective researcher, bridging the gap between research and the practice of law.
