On the network environment of the University of the integration of digital library resources

Paper Keywords: integrated network of university libraries of digital resources

Abstract: The University Library's digital resources for the purpose of integration is to improve resource use efficiency, saving the user time. Finished to complete the integration of digital resources, we need to use different search techniques and methods, these scattered , integration of heterogeneous digital resources into a unified environment to form a new unified seamless connection between the digital resources. the formation of integrated systems of digital resources should be available to the user a unified search platform, so that the entire search process for users is a transparent process of integration of digital resources is a primary issue for multi-dimensional links to various resources to solve the problem of Information silos. Second, is service-oriented digital resources for the purpose of the system build. the integration of digital resources is not a simple merger will be distributed heterogeneous resources together, and focuses on the integration of resources and services. This paper discusses the university library's digital resources, the need for integration, and integration of the principles of and content, and made a few for the University Library digital resources integration model.

1 Introduction
With the social development and scientific progress, especially in Computer technology and the widespread use of the network, the library has undergone tremendous changes. In the knowledge economy and Information age, people need knowledge and Information has undergone tremendous changes in knowledge and Information content and form of an increasingly diverse era, people need quick, timely Information they need to find the traditional library literature services face significant challenges in this changing environment, the library has also been a profound influence, the emergence of digital libraries in line with this change request. digital libraries based on information technology support, and digital technology and network technology to facilitate information access. The emergence of digital libraries, making the information in digital form for storage and transmission of information through the network, and to standardize the information to the management of the organization and distributed, but with the development of digital libraries, electronic journal databases, electronic library databases, as well as the emergence of various types of digital resources, management and use of digital resources faced enormous challenges because of these resources are used in various different companies different system development, makes these digital resources, data structures and platforms vary, so these data resources in a way is a form of isolated islands of information when the user of information retrieval time, must face a variety of different search interfaces and retrieval methods. With additional resources, the problem becomes more serious, so this study focuses on the integration of these digital resources, enables the user through a simple uniform search interface to access all resources.

2 University Library digital resources, the need for integration
In the network and the digital age, the proportion of digital resources in the library is gradually increasing. The advantages of digital resources, information retrieval and sharing of convenience, but as the type and quantity of digital resources increase, along with different database applications, content duplication, no association between knowledge, data formats and storage methods diversity, have greatly affected the data resources of the application. An important reason is that when users use different databases and network resources when he needs to enter a different system, repeat the same operation, so that wasted a lot of time, reducing the efficient use of resources, so how different databases to create a unified search platform and the integration of organic resources to become a university library in the process of building a primary task, but also in the field of information resource management a Research focus now, users of digital resources has become a favorite resource in the form of a university education in the university library plays an irreplaceable role in the effective use of university libraries, can be better for teachers and student services.

3 Library Network principles of integration of information resources
In this section, we give some of the principles of integration of resources to facilitate the integration of resources to guide the work.

3.1 Basic principles
Integration of resources is a basic principle is to maintain the integrity of information resources.

An integrated system should cover the internal functions of the various subsystems, reflecting the intrinsic link between the data.

3.2 Standardization principles
Standardization of principles, including standardization of data formats, standardized description language, the standardization of the index language and the standardization of communication protocols, security, standardization and database management software and hardware standards to ensure that information resources can be shared.

3.3 The principles of optimization
This principle is to make use of specific information resources, technologies and methods to be optimized to obtain the optimal organizational structure and storage capacity.

3.4 Security Policies
Security policy is to ensure the security of information resources, Computer viruses, hackers, software bugs, junk information, storage device failure, and so some problems may be the integration of information resources pose a huge security problem in the process of integration of information resources, We must pay close attention to information resources security.

3.5 the principle of continuity
The principle of continuity refers to the integration of digital resources must be a continuous process of development is only through continuous, systematic, dynamic process of integration of digital resources in order to maintain continued effectiveness.

3.6 The principle of three-dimensional
This principle refers to the digital library network of information resources integration process, and the user's information needs to be consistent. Information resources should be integrated to form a reasonable level, network-based, three-dimensional information resources systems to to complement each other and sharing purposes.

4 integrated library network of information resources content
As the network of information resources development and use of network information resources can be divided into different levels of these information is divided into zero information, an information, second information and third information. Therefore, resources and information integration and reconstruction should be different levels of consistency.

Zero is also known as gray literature literature it is not difficult to come into contact with public offering of the literature and it includes the government's administrative reports, scientific and technical reports, university and scientific Research institutions of the papers and internal publications, experts and scholars, manuscripts, conference information, social investigation reports, and more. These highly specialized literature, people need to read a very small area. Zero literature reflects the development of domestic and foreign scientific and technological Research and trends in China's reform and economic and cultural development process, these documents are very important resources so these resources should be classified and the depth of the excavation use to establish a special zero bibliographic database, making it through the Computer network can access these resources using remote online.

4.2 Reconstruction and integration of an information
Called an information refers to the network outside the organization for processing electronic information. Once information has a broad, rich content and various types of resources, therefore, is characterized by an information rich content, which requires us to information to choose, get rid of the extra useless information, select and organize valuable high-quality authoritative and reliable information on the Web. For the time information, we can use the text mode, text mode and ultra-site model for family organization.

Text mode mode is mainly used for the construction of full-text databases, full-text outside of the network information collection and organization, to form a new input to the network resources used to organize hypertext mode on the network-related information, so that the user can either node to access relevant content. Mode is mainly used for personal family website information organization.

4.3 Reconstruction and integration of secondary information
Secondary information is information of a rich, refined processed product which is the publication process tools to facilitate the use and management of an information when the network of information resources can not be automatically converted, it must adopt some relevant knowledge, theory and method of information organization to create online information retrieval tools, such as information resource chain to control the text, hypertext and family website to access an online information is now the second-line information on the organization primarily through search engine to complete. search engine is a class of sites on the Internet. Its main task is information on the server automatically search, classification and set the index and the index of the contents stored in the database. search engine now made expansion direction is full-text search, which can generate a comprehensive text on the page of the site, to provide a new powerful search function by which the content can be retrieved directly from the literature. The engine supports multi-perspective integrated information resource use. full-text search technology is a foundation of information can be found, information analysis and filtering, and information security controls. to full-text search as the core technology of the era of Internet search engines to become the mainstream technology, accurate and fast is the full-text search system The key elements for the integration of information and the second reconstruction, we must choose on the Internet to the literature we need, according to a uniform format, and knowledge of the relevant literature to set the connection. In addition, we need to develop a software automatically conversion , auto search, auto-generated directory, allows users to automatically extract keywords for the website in a traditional automatic identification and organization. and then one, we should establish a database image, the external data in the local server to provide the latest A copy of the literature.

4.4 Reconstruction and integration of the three literature
Different search engines offer different search methods and implementation, in a short time in order to help users quickly find the right search engine, we can use the chain to the literature on the site of the secondary literature on the formation of three documents, in order to improve the efficiency of future retrieval and utilization of network information resources.

5 digital resource integration model
The integration of digital resources is a systematic project, consideration must be integrated in all aspects, each university library should find a suitable integration of their digital resources to improve the method efficiency in the use of digital resources. University Library digital resources integration can be divided into several different ways:
5.1 Links Integration
The integration of digital resources is the easiest way. This provides the resource dynamic link, through the use of hypertext links to the network, allowing the user may be another extension services.

5.2 based OPAC system integration
This integrated approach is in the phone directory data as a core technology, which can be divided into two modes: internal and external directory of directory integration.

5.3 The integration of electronic resources navigation
This approach is the search portal for digital resources together to create a resource navigation database, it can be by name, theme, etc. to find the necessary resources. This integrated approach is relatively simple to implement, is now a lot of University, a widely used method.

5.4 Subject to guide the integration
This approach is a knowledge-based classification system navigation. According to a standard and the need for online resources to collect and organize, to form a unified interface, providing access, browse and link services.

5.5 Integration of heterogeneous database resources
This method is the integration of the navigation direction of future development it through a unified search platform, to provide one-step cross-database search service.

6 Summary
With the Internet and digital era, the library's resources through a huge change because the easy sharing and retrieval of data resources, their growing proportion in the library. Through the integration of data resources, users can search through the Internet in the library search homes on the platform to the desired resource.
