In this paper, we discuss the characteristics and problems, improvement of linked textbooks in conjunction EBS policies. EBS textbooks are also linked with a comprehensive set of reference books gifts. It can be regarded as very practical teaching material that can efficiently teach and learn in a short period of time. If not to a direct contact with SAT, EBS linked textbooks may in itself be of high quality textbooks referred to. EBS currently associated textbooks can be said to choose between concept learning-centered approach and attack the problem type approach. Based on the properties of the EBS linked textbooks, more ways to improve the linked EBS textbooks as follows. First, we must think complements rather than substitutes. Second, we need to reset the connection method of the SAT. Third, we must retain the quality of textbooks to contain various language materials. Fourth, we increase the quality of the text questions. In conclusion it is, if we make a connection more than 50% in conjunction with the indirect ways, we will be able to maintain a policy linked EBS without a large friction with public education.
