In order to facilitate the process of the development of S & T intelligence work, the S & T intelligence work is now divided into four periods. First, science and technology intelligence work in the prehistoric period, also known as the library literature period, and then the formation of science and technology intelligence work period, the third period is the development of science and technology intelligence work, finally, briefly talk about the fourth Period also
