Bumping this up from a comment.
From the Oelibrarian blog, an entry entitled Just desserts on bare feet.
The author is “a fairly new, tenure-track faculty librarian.” The author also hates bare feet, saying
If you are a follower of this blog, you know I am virtually militant about the no bare feet in the library issue and don’t hesitate to tell students they need to wear shoes while in the library.
Whatever for? Who cares? Why should you care? What problem does such a ban solve? None. None at all.
It seems like librarians are among the worst authoritarians for telling other people what to do for no other reason than that they like to order them around. Libraries, more than any other governmental entity, seem to like to ban bare feet. I did an internet survey a while back (using Google and other search engines to find libraries’ codes of conduct). Approximately 2/3 of public libraries have a shoe rule, and approximately 1/5 of college libraries do.
In the comments, the author adds that no bare feet is a campus-wide policy. I really have doubts about this—I have never heard of a college or university with a campus-wide barefoot ban. What do they do in the dorms, for instance? By the way, the author’s part of the state university system of New York, which makes me doubt it even more.
PS. My daughter is a librarian, so this is no knee-jerk antipathy to librarians, just those who are more impressed with their own self of self-importance and who succumb to their authoritarian impulses.
