Reflecting the conventional education of library science, I compared it with documentation, management of information and management of documents similar to library science. We find that the core of library science is Retrieval system or Secondary communication of which functions are communication and memory. In addition Retrieval system is analyzed in three functions; search of information, storage of information, organization of information, and through them there is identification of information. On the basis of the above view, I settle the required subjects; (1) Communication (2) Search of Information (3) Prepareation of Materials (4) organization of Materials (5) Management of Information activities (6) Practice.
