For a long time, people have been accompanied by paper documents. The production and utilization of paper documents have formed a fairly perfect and stable system. Long-term reading, as long as the light is natural and soft, has little effect on vision and has a good reading effect. Therefore, paper documents will continue to exist for a long time to come.

2, easy to save

The carrier of paper documents is integrated with information, and its information is also protected while the carrier is preserved. For a long time, people have accumulated rich experience in preservation. As long as the temperature, humidity and illumination are properly controlled, paper documents can be preserved for a long time. The instability of electronic documents and the limitation of information preservation make paper documents shoulder the function of preserving human literature information.

After thousands of years of baptism, paper documents have established a perfect and developed editing, production and distribution system. In terms of scientific evaluation function, all book publishing departments have established and improved academic evaluation committees or similar institutions to ensure the academic level of published documents.

With the rapid increase of literature information, the storage space of paper literature and the information contained in the literature itself are limited to varying degrees.

Paper documents are prone to deterioration and natural aging, and the reproduction of their knowledge content requires a lot of manpower and time.

Paper literature itself contains little knowledge, and a lot of related knowledge needs to be loaded on a large number of paper carriers, which is not conducive to people's retrieval and utilization.
