This book addresses more than 85 of the most crucial changes contained in these codes. Each change analysis features the affected code sections and identifies the type of change: newly-added text, a modification ofthe existing language, or deleted text. Accompanying each change is a detailed illustration, relevant photograph, or practical example, which clarifies some of the technical jargon and makes the content more relevant. The book's attention to detail, its logical organization, and its thorough yet concise coverage all make it an ideal tool for transitioning from the 2009 codes to the new 2012 versions.
