As a CPA professional in the Internal Audit field, I deal closely with Sarbanes-Oxley matters within my organization day in and out. This is a great "one-stop" reference tool for me and I have found it very useful. I highly recommend it to those with all levels of experience in working with Sarbanes-Oxley!!!.
