Currently, the development trend of new materials science and its applications in the field of advanced manufacturing are as follows [4]: (1) Develop from homogeneous materials to composite materials.
In former times, only the metal materials, polymeric materials and other homogeneous materials were often used, but now such composite materials composed of metal materials and polymeric materials are being used more and more.
To support the development of advanced manufacturing technology, during the period of the “Eleventh Five-Year Plan”, according to National Long-Term Science and Technology Development Program (2006—2020), National Plan for the Development of Science and Technology of the “11th Five-year Plan” and Development Program of 863 Plan in the “11th Five-year Plan” Period, in the research of new materials technology, our country has set up five major research projects, respectively as follows [5]: (1) Design of intelligent materials and advanced preparation technology; (2) high-temperature superconducting materials; (3) nano materials and devices; (4) photoelectric information and special functional materials; (5) high-performance structural materials.

And university library is necessary to utilize modern science and technology , advanced computer technology, high-density storage technology, multimedia technology, network technology, communication technology and information media to share documentary information resources with public.
Along with the rapid development of reform and modernization, science and technology has also attracted worldwide attention.
In their spare time, they rely on internet to seek or download materials or data they need, which is a more convenient and cool way for them.
The development of applied technology exerts a deep effect on the storage media, copy technology and transmission ways. (1) Change of library storage media.Firstly, the raw storage media are such natural materials as oracle bone, animal bones and the inscribed bamboo slips.
