Dear Professor Cook. Following your data and calculations avidly! Might i point you to a useful resource that has just gone live on the internet. WolframAlpha bring together power of curated data, with the ability to perform some math on it. Could be a useful tool moving forward.

Renee,

I compiled these data from SEC filings reported in S&P COMPUSTAT date available online at Wharton Research Data Services [WRDS]. The 2007 data are not yet available from that source but you can get them from EDGAR OnLine I*Metrix. The metric and its measurement are described in my book. Let me know if you have any other questions. Thanks for your interest.

I was wondering where I can get the graphical information listed above for the year 2007? There are no references above. Thanks!
