I mentioned both of these briefly over on You don't look like a librarian! but I know everyone doesn't check there (not that I'm deluding myself that this gets read a lot!) so I wanted to mention them again.
* InfoSciPhi has written a great article about the librarian as a Wise Old One archetype. I really liked it when I found it back on May 1st (wow, that seems so long ago already!) and I still like it today. Go forth. Read it. Try to be wise.
* Librarians: We're Not What You Think is a great web and PDF rant originally published in 2002. I found two claimed authors so will acknowledge them both: John Hubbard (HTML) and Jerry Whiting (original PDF mentioned on YDLLAL).
Still only 90°.
