I found this book not to be a good investment. It is an extraction of certain SSA publications, all available in user-friendly format at the official SSA website. The major drawback is that the tables of values for benefits and earnings limits stop at the year 2002. The edition I received in January, 2003 is the third edition dated May, 2002. While the content is current to 2002 and the SSA regulations may not have changed substantially, it is not helpful for referencing 2003 numbers and beyond.
