As Mr. Tardi indicated earlier, there are other proceedings where testimony has been given under oath that may give further indication of how the testimony given here was false or untruthful. I suppose in a sense the advantage you have is that the committee was the first step, so all the other stuff came later and makes the comparisons easier.
Mr. O'Neal of the library might better estimate how much time this would take, depending on how far you want to stretch your inquiry, whether you want to include the testimony in these other venues or whether you want to limit it to a contrast between the committee and the Gomery inquiry. But it could take some time, admittedly.
