This library location is pretty good. I've used it a lot through high school and starting to use it again to study have a good place to go free from home distractions and chores.
The area I use the most is the table area, but it can get quite loud sometimes depending if there are study groups - but usually everyone is pretty respectful.
I felt really dumb the last time I came after work to study some material. And spent a lot of time studying the area in the corner that said "Cell Area" and right below it was a map of the city of Charlotte. It took me a while to figure out why the library had a cell phone map covering the city, but those two things were separate. I am pretty positive that the map was there first and then a courtesy "Cell Area" was placed there in the corner as to not disturb too many people in the quiet zone. I still feel pretty stupid about how much time it took me to come to the conclusion.
