The library is a very good place to study. I go to the library once in a while if I want to change my study environment, or if my house is too noisy, or if I have to wait for an hour or more at school until the next lecture starts. There are a ton of other reasons to grab your books and study an afternoon/morning at the library.
What I like most about studying at the library is the fact that the library is usually very quiet and there is an atmosphere there that makes you concentrate on your work easily. There are usually more students working there which is very motivating for me.
I usually go to two different libraries: the university library is the place I go to if I have school, and want to study a little bit more. The library in my hometown is the library I go to if I don’t have any lectures (I refuse to travel 2 hours to go to the university library if I can study at the library in my hometown as well).
