On the Network Library Collection Development in the
 
 
【Summary】 computer information network structure of information resources to the library environment, library resources and access to quality assessment methods  price standards, information resources, support methods, financial and other aspects of the purchase collections brought profound impact. Adapt to changes in network  environment, the library should be updated in the collection development in the concept of traditional books, the rational allocation of resources and network resources  collection sources, enhancing collection of resources and division of labor characteristic construction coordination, and establish a society of information resources security system, increase input in the building  information resources, and strive to improve the quality of library staff. Key words  Network / Collection Development / Reference Resources  body】 【 library collection is the library providing information services on which the resource base, and the development of library collections, always  by the social, political, economic, scientific, technological and cultural environmental factors and constraints. The information currently in the ascendant wave of  network, the development of the library collection will undoubtedly bring significant and profound impact. Analysis of this effect, to explore how to establish network environment  library collection development strategy for the turn of the century an important issue facing the Library.  A network environment and library  computer and modern communication technology, for mankind to create a new information environment - Network Central  environment. The so-called network environment, refers to computer and modern communication technologies built on combination of broadband, high  fast, comprehensive, wide-area-based digital telecommunications networks. This network is hosted by Network network, Internet connectivity can cover one country,  several States and the world (Note: Xie Yang Group: 97, No. 3..) In a network environment, the traditional way of information provision and access to a fundamental change of location scattered in different  information resources stored in digital form, interconnected by communication networks, people can make use of a terminal for the network office  needed information resources. This information network is no longer a separate entity, or information storage place, and  is a virtual user-centric information system. In this information system, information resource is dynamically through the network  to carry around the user's specific needs, information retrieval, acquisition, processing and use is based on user needs , through a flexible coupling, called all kinds of resources and systems integration to complete. Users as long as their computer and network connection  access can be restricted by time, location of impact from the information and easy online search, select, obtain their required information .  International Computer Internet (Internet) the rapid expansion in the world, marks that form a network environment is . Internet users on an unprecedented scale, information resources and information systems linked to provide a range of information resources  association, organization, retrieval mechanism and information delivery, service forms, such as e-mail services, bulletin board services  , remote information retrieval service system, file transfer services, electronic document publishing and retrieval services. Currently In  ternet users in the world reached 70 million, and is 165% annual growth in the global spread, adding Internet  has reached 175 countries (Note: Zhaopei Yun, Zheng Shurong: the and the Internet This international network is the computer communications of many worldwide computer network and computer  banded together to achieve interconnection of information exchange and sharing of resources. Face of the global information network  trend, China is also timely planning information network construction process. At present, China has built a China Public Packet Data  Exchange Network (CHINAPAC) and the Chinese public digital data network (CHINADDN), on the basis of established national public economic information communication network  (Golden Bridge Project) has started. The country's largest computer network - Education and Research Division  computer network (CERNET) has also been built and put into use. It is inline in major universities, research institutes,  technology information institutions, Internet outreach, and global integration of modern information network. All this shows that the network environment has not  distant dream, but is approaching reality.  Network environment the impact of the library is extensive and profound. Information network to make the library's resource base Tupo  the traditional  Library Network provides a broad space for development of information services, such as through electronic document delivery to provide a source of library  carry out interlibrary loan, receive and provide reference service; libraries from a large on-line databases, electronic journals, electronic forums and electronic bulletin board to find, collect applicable information, then use the Internet for customer service, but also in  own system to create an electronic bulletin board, collecting all kinds of public information release, the book Hall became the community or campus information  release sites. Returned to the library network environment provides a literature-based electronic data interchange interview, based on the number of  central bibliographic database of shared cataloging, OPAC retrieval based on the flow of services and data communications on a variety of other information services. However  However, the library network environment poses a severe challenge. Conservative and traditional library thinking to run a library closed, re-possession of the books with the concept of light  to read the flow of collections-based service model and the backward technology and equipment and the traditional manual method , etc., have been difficult to adapt to the network environment. The challenge of how to take countermeasures library,  will be directly related to the network environment, the survival and development of libraries.  Second, the network environment, the impact on library collection development library  impact on the network environment is multifaceted, and the impact on library collection development is also very obvious, with the body reflected in the following  aspects:  1. on the structure of library information resources  the rapid popularization of the Internet not only greatly enriched the library's resource base on which to provide services, but also the structure of information resources  occurred important changes in the traditional sense of library information resources, library collection is the result,  collation, storage and have Today, people access information from the Internet, although different from the collection  resources have Therefore, the book  Museum collection of information resources can be divided into two parts, resources and online resources. The reader needs to obtain certain information , regardless of the library collection, or obtained through the network access, the quality of the information itself, and no difference.  Only easy access to information, easy access, the reader need not take into account the location of the information stored far away from their own. Therefore , for libraries, online resources and library resources have the same significance. Moreover, network resources are very rich in , access to convenient, and thus will become an important basis for library services. Such as Hong Kong University of Science and Technology Library print journals  2,200, but provide as many as 34,500 kinds of electronic journals (Note: Li Ximing, etc.: 5, 1997.). It can be said, in a network environment, each book must be in the collection  Museum resources and online resources to find the best combination between the points.  2. On the way of access to library resources  library access to information resources in traditional ways, primarily through the purchase, exchange, donations and other ways to get the text  offer. Tibet literature, the library will have the documentation of permanent ownership and use. However, library resources on the network information  access, the situation is different. Library access to electronic information through the network more often than not information resources  body, but rather the right to use the network of information resources. Access to information, there are acquisition, network, online tenure, rent ,You are not allowed to view links. Register or Login, exchange and free and other means. Access to these new methods of information resources, new technology, equipment and professional technical  technical staff.  3. Evaluation of the impact of library resources  traditional library information resources collection development is mainly the construction and evaluation of the quality of the collection, the main reservoirs around the museum  quantity, structure, focus, utilization and other aspects, the evaluation object is the collection of literature itself.  Ring in the network environment, the evaluation of library information resources, not only the quality of the actual collection for the evaluation of museum objects, but also the access network in the world  information resources. Because users expect the library to provide better and more timely and more accurate  information services, rather than the drop in the ocean like a Hall of Tibet. According to this evaluation criteria, the quality of the collection was seized  quality cable to replace. Here, the search quality is the degree to meet the readers, the object of evaluation literature (information)  delivery rate.  4. On Security Model of Information Resources Information Resources  establish a social security system is the intelligence community over the years to book the goal, but for various owners, the reasons for customer  view, the construction of information resources actual operation, the library is still a self-protection mode.  Network in the network environment, this security model is completely suited to the. Network construction of library information resources in the proposed coordination of the division of labor  urgent requirements. Because when a library's holdings into electronic documents through the network and provide services to users , other library collections and then the same processing, the Internet, has become superfluous. Network environment to the same location in the library is not  the mutual use of information resources, sharing of resources. To ensure a comprehensive online information resource , adequate and systems to reduce redundancy and waste, the objective would require libraries must abandon self-sufficiency of the information resources
