There are 5 publications about Quality control of lectures on the web, and we have published all of them. During the past few months we have begun to understand how best to shape a QC system so that scientists are best able to find the lectures that they want. We have discovered that it is best to let the scientists themselves decide as to what criteria to use. Some faculty will want to look only at US Scientists, others may want to know how students rate their lectures. We will employ a personalized quality control system.
