Who Are You People? is a recently released book that looks at several subcultures of "passionate fanatics", including furries. The Furry chapter is quite good -- I recommend it to all.
After updating the book's WikiFur page with a summary of the furry chapter, I wrote to author Shari Caudron to let her know. She, in turn, posted about it on the book's blog. WikiFur founder greenreaper posted about the exchange in the wikifur LJ.
Small victories. :)
