I've mentioned on here a few times that I became a librarian because when I was a boy my local librarian sometimes wore a kilt and wellies at work, and I wanted a job where I could do that. There was more to it than that, of course. I distinctly remember being greatly impressed when I asked him for books on ancient Egypt and he took me directly to the appropriate shelves. And the way he could rifle through the old Browne tickets and find my reader's card was memorable.
That librarian's name was Roy Flatt, and I'm saddened to read that he has recently died. I never did get round to emulating his sartorial approach, but I may just appropriate his answer for preferred leadership style.
