More New Pages

Here a few more new pages that have been completed:

http://ulm.edu/~niemla/done-kn/subjectlibrarians.html

http://ulm.edu/~niemla/done-kn/reference.html

http://ulm.edu/~niemla/done-kn/friends.html (just light editing)

I've also made some small fixes on the database pages. Nothing major, really.
