As a humble guest of the LOC I am responsible for conducting research for my online magazine covering news in science and technology. Usually i do my research work alone and since i am pretty well educated have learned where to search for resources. However yesterday i unhaply remarked to the librarian that she has a peculiar way of only primarily aproaching white visitors for asking if they need any help. She ignores people of color. When i asked her about this she turned on me in a nasty cold manner. "I have never seen you before....if you continue talking about this i will report you and confiscate your library card!" This was said to strike the fear if God in me of course. Of course she has seen me before, but evidently I am supposed to be content about my invisibility. It was a humbling experience. I did finish my research but now we know there are categories of visitors of course just like at the national zoo. Would you rather be a panda bear in the zoo or out in the wilds? What a dumb question!? After all they really have a top notch reference selection.
