1Analysis of the network model analysis of Library ServicesPaper Keywords: library service model network environment Abstract: Information technology changes the way people work and live, the network environment, this paper analyzes the characteristics of library information services, provides updated service concept, improve the quality of librarians, deepen the construction of information resources, providing readers with personalized service service model. As information technology and network technology, the library in the midst of the global network environment, the individual is no longer an isolated network environment, the information needs of a wide range of readers, the library includes both the traditional paper-based collections literature, also includes on-line information resources. information technology and network technology to break the pattern of library services, library services model for his proposed new challenges. 2A traditional library service model Traditional library collections in the main paper as the carrier of literature information, is to collect, organize, store, transfer document information society cultural institutions. Library officials use the museum collections, to provide services for the reader the traditional library service model has the following characteristics (1): 1.1 Passive Service Traditional library services to library-centered, passive and other readers to come mainly of services include: museum readers to read, borrow books, documents copying and reference services, etc. As a result of the mechanism, the quality of personnel and equipment limitations, service work has many limitations, but also inhibited the enthusiasm of the staff and the spirit of active service. 1.2 Low level of documentation services Traditional library to collect, organize, preserve and transmit the information-based literature, services are mainly provided to the reader to borrow the original literature of library literature did not make a deep processing, the formation of secondary literature, and 3even the three documents, not fully tap the knowledge of the original document information. affected the reader the scope and level of services is severely restricted, limited to low-level service, is not conducive to the reader access to information on demand and use. 1.3 closed construction, waste of resources Traditional library management system by the constraints of the formation of small, large self-isolation of the library model, each library is trying to establish their own relatively unique and perfect service system, in particular literature resources construction, the same area, different kinds of resources with the library to purchase a common phenomenon not only a waste of financial resources utilization is also low. Meanwhile, the management system, and do not give full play to the role of literature resources. 1.4 body structure As belonging to different administrative authorities, the direction of running the museum library, business development and audience, staffing and funding determined by the higher 4authorities, and therefore, the library has become the acting executive authorities, and social needs, political and economic out of touch. 2 reader service network environment, the characteristics (2) 2.1 diversify the reader needs As information technology and science and technology development, knowledge of the competition and cross-disciplinary knowledge, penetration, user demand for information to show diversity of knowledge innovation and re-making the subject highly integrated, highly knowledge-intensive, readers want to access a variety of sources and through process by the comprehensive information the reader is no longer just the information needed public offering of books and newspapers, including the conference papers, dissertations, and other non-public offering Chorography information. With the development of computer technology, expansion the form of a document carrier. Readers not only to the library to borrow the paper books, but also need to pass documents on the network remotely. 52.2 Sharing of information resources Network environment, the library as a Internet space, breaking the boundaries between the traditional library. Library Resources to the resource sharing direction, and each library is a node on the network, each adding network of units and individuals within the system can use any network library information resources, information resources of each library is no longer a one island. 2.3 Information Management Automation Computer technology in the library application, making the literature of information collection, collation, storage, retrieval, delivery and business management automation. Use computers to manage multimedia information resources, especially for video and digital audio information storage, processing, processing, image retrieval and transmission, improve resource utilization
