Not sure about you, but I was surprised a little to see the books that made it to the top. On the other hand, the search results included all references starting with 2003, so potentially popularity of some books is inflated as others were not yet available back then. But again, at the end of March we will release the updated ranking that will reflect only results for March.
I am not sure how to best post tables in the forum, so here is one version and also another version with links at the bottom:
