Abstract
This paper describes the concert of digital library and its social function services mainly discusses the technology architecture of digital library according to its technology classification. It can give good reference to build a digital library.
Keyword: Digital Library, Information Technology, Technology Architecture of Digital Library
1. The Concept of Digital Library
There are many explanations about the concept of digital library now.
For example, the digital library system is an electronic access service technology to collect multi-media information such as image ,text , voice , audio , portrait , vedio, TV , software and scientific data which has high value, to organize normal process, to preserve and manage well ,to improve knowledge and to provide high speed strides interlink age over database on LAN. At the same time ,the system is in relation of a solution of a series of problems, such as intellectual property rights protection , access authority , and data safety. The characteristics of digital library are collecting digitalization，Handling with computer , delivery in network, information stores freely , resource share and structure linking up-rization. ----Wenbo Xu \"Chinese figure library- figure resource exploitation and research \".
The construction of digital library is to transfer variety multi-media information to huge numbers of families on the basis of unified standard and normalization , on the bottom of various digital information，on the hold up of the resource warehouse group of distributed great capacity data, with the intelligence retrieval technology , on the mode of Electronic Commerce supervisor, on the transmission passage of broadband high speed network. It deals with figure information resources production , precession , store , retrieval , delivery , protection , use , achieve and deletion.----Chengjian Sun, Gang Liu \"The starting and development of the Chinese figure library construction\". Everyone can access all the knowledge in any time by any digital equipment which links to the Internet everywhere. ---Special USA figure library group \"Digital Library: Commonness to human being
knowledge visits \".
Another concise explanation is easy to understand for readers. That is: the digital library is a information system that takes data base as basic way using the IT to organize digital data information and to provides server to consumer via the network.-----Yonglin Cui \"The theory and application of the digital library \". This definition has several parts as follows:
(1) Having explained that digital library two main part works of the content: carrying out digital data organization and providing services
(2) Have explained that the basic way of digital library to organize digital data is to build a data base. (3) explained that the basic technology is IT (mainly computer technology, communication technology and network technology)
(4) Have explained the condition of the digital library is network of digital library
(5) Have explained the object of the digital library is consumer or in other words the position of a consumer in the digital library.
(6) Have explained the serve way is interactive access.
(7) Have explained the digital library is a information system that has complicated architectural.
(8) Have implicated interactive relation between digital library and the social environment
The various concept and definition explain in the digital library from different aspects. No right or wrong, but analyzed these concepts , we can know that our Internet is more and more close with us, and me can enjoy better library service in a digital library.

The Social Function and Services of Digital Library
The social function of digital library include : preserve cultural heritage, knowledge dissemination and information exchange, improve national culture quality , bear the weight of figure culture , support knowledge innovation
Preserve cultural heritage
In tradition , the human being cultural heritage in the library is the basic social function, but ought to preserve human being information resources in digital library. In the field of the cultural heritage preserving human being, the digital library has absolute advantage with new technology means, not only to resolve the day by day grave mansion hides insufficient pressure of space, but to make a long range perplex the library worker difficult problem in the field of the data preserving the costly document that the mansion hides managing to solve. Not only have resolved the problem preserving forever, and can open to the outside world to the public, making full use of its worth, have resolved the contradiction with preserve and utility.
Knowledge dissemination and information exchange As the knowledge gathering together field , the
information key position, the digital library play spreading knowledge and exchanging the information function. Especially, the digital library already , makes original one-way delivery become two-way exchange , makes the feasible consumer accepts the space-time restricting on network connection no longer , realizes that customers can communicate with others by convenient rapid various networks. Certainly, the digital library must use with network guide with convenience of customers from gaining required knowledge , having the effect of guiding to the network in voluminous information resources.
Improve national culture quality
The advancement of society is depending on people's quality rise , in the process of which digital library plays an important role. In the respect of improving civil information accomplishment (a consciousness and technical ability gaining , appraising and using information's in studying , working , living), the digital library becomes the information service organization guiding the public to realize information resources and value , learning to express information need , being good at making use of information resources. To part public, the digital library becomes a channel to gain important information. The digital library carries out the ability of information education initiatively , arouse people gaining the information sense of urgency , enlarge by the depth serving for reader, try one's best to provide various information to reader, accelerate information delivery, making the extensive consumer can pass to what be needed information seeking and track down , training oneself to gain information. Bear the weight of figure culture
That digital culture is a culture form showing with the digital form . It is one kind of mass culture and a one kind of culture that low cost operates which has the characteristics such as publicity and opening to the outside world , so it has extremely superiority as a result and is taken seriously by people also even more. The digital library becomes important figure culture carrier because of the great quantity information storage. Support knowledge innovation
The digital library is a result of knowledge innovation , and it also has the function supporting knowledge innovation conversely. It may play a unique role in developing and expanding scientific spirit and science thought , such as the scientism basing on facts , digging into assiduous and never tired assiduously vigorous ,the innovative spirits daring to explore and so on, and respecting knowledge , respecting talented person, including respecting intellectual property rights. The digital library improves readers knowledge level ,changes the structure of knowledge, broadens the knowledge range, cultivates readers capability by its information server. It is the best approach to improve readers intelligence.
Digital library service comes to embody mainly by the fact that digital resource serves system. Digital resource serves system integration the following key
