I might do this at some point, but don't want to do it twice. If Patashnik hasn't released a new BibTeX by this time next year, I will probably go with "misc". I do agree that LWN deserves more respect, but on the other hand, RTFP.txt has been using "unpublished" since January 2008, so I am willing to hold off another year. ;-) Thanx, Paul
