Vatican Library is one of the most famous libraries in the western world, and also a world-famous academic library of humanities, which mainly collects theological books. Non-religious books include art, architecture, language, literature, historical philosophy, mathematics and science, but in terms of its depth, its coverage of social science books is slightly insufficient. Many works of Vatican Library have played an important role in the revival of classical Greek and Roman culture. At that time, the library was a catalyst for the progress of science and geography, and its collection reflected its contribution. At the same time, the library is also the driving force to make Rome a political and intellectual power center.
