It was just an affront for a person who works at a library to pronounce it liberry. Like when someone says "should of" instead of 'should have'. Or "me and him went to the store". It's an assault on my ears
We normally pronounced it libree.
Actually it's a bit like Tottenham being pronounced Tottnam.
Actually in both cases we do pronounce it library and Tottenham but we run the syllables together and don't enunciate them so it sounds like libree and Tottnam.
Funny thing - I worked with a woman in the library who pronounced it 'liberry", can you believe that?
Now, that would make for a cute bookstore cafe name, Liberry.
