Original HMI? Reports

How Much Information? 2009 follows two University of California, Berkeley research studies, HMI? 2000 and HMI? 2003, conducted by Professors Hal Varian and the late Peter Lyman. HMI? 2009 builds on the two Berkeley studies, but uses different definitions and measurement methods. Below are links to the original HMI? 2000 and HMI? 2003 reports.
