In this major reference collection, accounting theory is taken as the basic assumptions, definitions, principles, and concepts ? and how we derive them ? that underlie accounting rule-making by a legislative body as well as the reporting of financial information. This major work starts with a philosophical overview of accounting, including accounting theory. Among some of the other issues examined are whether accounting is an art or a science and whether or not it can be value free. Also examined is the question of whether any "preconditions" are necessary to establish a viable approach to accounting theory.
