We need interesting books, we want to know answers to our questions. All this we can find freely in libraries.
Yes we use our school's library. Because reading is more interesting with our friends. We can also share our knowledge.
I prefer using and libraries and Internet. First of all Internet isn't free, but we can find answer to the question fast. Library is free but you have to look for the book which you need. If you want to relax of reading, I prefer reading books. There pages after pages.
