Theodore P. Seto (Loyola-L.A.) has updated his monthly rankings of the Top 25 U.S. Law School Tax Faculties, as measured by the number of SSRN downloads (through 9/1/06):   

I’m still working the bugs out of the system. I now have Yariv Brauner back at Florida, not Arizona State. In addition, I’ve added Donald Weidner to Florida State’s tally. These faculty changes account for all of the changes in “all-time downloads.” Otherwise, the “all-time download” rankings are unchanged from last month. “Recent downloads,” of course, are much more of a “What have you done for me lately?” phenomenon.

SSRN tax faculty ranking changes since August 2006:

For purpose of Ted Seto’s analysis, a tax professor is initially defined as any law professor at a U.S. law school (1) self-identifying with one of the tax categories in the 2005-2006 AALS faculty listing, (2) who has posted at least one tax or tax-related article in abstract or full text on SSRN. Paul Caron’s listing of 2006-2007 new hires and lateral transfers is also reflected. Further corrections are also made as requested. As is true of Paul Caron’s ranking of individual tax professors, downloads of all SSRN postings of any tax professor, so defined, are then tallied.
