Our colleges have large academic libraries. These libraries are for the use of college students, professors, and researchers. Academic libraries are used mainly for doing research like studying the solar system or how earthquakes happen. These libraries do not have the same types of books you would find in a public library.
The earliest known library was discovered in Iraq and belonged to the ancient civilization in Sumer. They didn't use paper books but instead wrote everything on clay tablets using a style of writing called cuneiform.
