Very cool site for those of you in academia needing to cull the newest fad of the h-index from Google Scholar.
The quick explanation of the h-index is that you have h publications with at least h citations. In other words, an h factor of 3 means you have 3 publications with at least 3 citations each. A h index of 25 means 25 publications with each of them having 25 citations a piece.
Who knew I had an h-index of 11? Web of Science, the normal index for such things give me a 4 but they are heavily journal-centric. Pretty sweet and I should have put that in my tenure package.
