The Information Service is a focus and hotspot issue of research in the field of library science.At present, the number of network information resources growing exponentially on the network, every user can be added information, resulting in uneven quality of the information.Users in order to find what they need information on the network using traditional methods, the degree of difficulty is no less a needle in a haystack.Moreover, the user demand for information of a single tradition of the past into a diversified...Synchronous trends of the information environment and information users’needs, in order to satisfy customer demand, the new service in a variety of personalized services, value-added services, user-centric information integration services, etc. continue to rise and continuous development.Subject Information Gateway (the Subject Based Information Gateways, the referred SBIGS) In this case, and developed.The subject information gateway can be understood as a new organizational model of information resources, the model for network information resources.The subject information gateway through the collection, integration of academic resources of the network of a subject area of expertise, and through the Internet to provide users with the information service platform for information retrieval and service.It effectively solve the deficiencies of the traditional and popular search engines to find the professional and scholarly information, enhanced targeted to improve the precision rate, subject information gateway to many professionals, teachers, students and academic staff to find informationa great convenience.Due to the academic rigor of the discipline of professional information, making it different from the public information, it is difficult to search and find, increasing the coefficient of difficulty of the user.For now, many university library have to carry out the work of the organization of network resources, the subject information gateway for the needs of users, according to the characteristics and nature of the school, we look at the subject portals have been built, there are many excellent subjectsportal to provide customers with a lot of convenience, but overall, there are different levels of inadequacies, such as single link to this site too small, retrieval way or no way of retrieval, the network connection is not smooth, ignoring the updating and maintenanceredundant construction, monotonous, the good and the bad quality and other issues.Therefore, the subject information gateway to China has built the status of the investigation and analysis, to identify where the strengths of the analysis of defects and deficiencies, to provide a reference for the construction of the subject information gateway after, which is the significance of this study.The purpose of this study is to investigate the construction of the Academic Library Subject Information Gateway and service status, identify existing problems and deficiencies, and to find solutions appropriate countermeasures, to explore the future development of a subject information gateway servicesThe trend to provide appropriate advice, information portal building for domestic and international disciplines.This paper uses a literature survey, topic analysis, questionnaires, case analysis, research methods, comparative analysis and network online experience. The specific contents of this article are as follows:1.An overview of the basic concepts of the subject information gateway, to develop an overview of the characteristics and types.2.Foreign well-known construction of the subject information gateway and services that already carried out research, and service functions to see the detailed presentation summarizes the status and characteristics of the foreign subject information gateway.3.Domestic colleges and universities subject information portal construction and service status quo investigation and analysis, summed up the characteristics and shortcomings currently showing.4. improvement strategies to enhance our university library in the subject information gateway building.
