An indexed list of resources from a librarian by trade was inevitable. Of course, this librarian did not take ontological studies so the classification schema here is already under criticism.  Please note that some links lead to abstracts rather than full articles.  Check with your local libraries or friendly neighborhood librarian if you’re unavailable to locate free, full-text versions.
