Abstract: cloud computing with its unique concept for the university library's development has brought new opportunities, this cloud-study, analysis of domestic and foreign libraries use cloud computing results, combined with the reality of university libraries situation, focusing on cloud computing for the changes brought by the library Information services, and to explore the university library in the cloud computing applications need to be resolved.


2009 is known as "cloud computing first year," Cloud computing has been strong in this year's development, despite all the standards, norms, systems are not perfect, the pioneer of all walks of life are still shouting into the "cloud" This has been static in the library of knowledge and learning also led to no small vibration. With cloud computing Technology and the continuous integration of library services, such as in front of the library, what kind of future? as a library The most abundant of the university library resources, how the face of cloud computing to the challenges of library work?
1 The concept of cloud computing
1.1 What is cloud computing
I believe most people are already familiar with the term cloud computing, but how to understand what cloud computing it? Since the birth of the concept of cloud computing, a number of domestic and foreign scholars to study, because the background of cloud computing Technology and the driving force is more complex, researchers have not quite the same background and outlook, so far not a single cloud computing recognized standards definition of domestic scholars Peng to the definition of cloud computing is "computing tasks will be distributed in the form of a large number of computer resource pool, so that all applications to obtain necessary computing power, storage space and a variety of software services." Wei Zhipeng that cloud computing is an Internet-based super-computing model, that is distributed in a variety of servers, PCs and even mobile phones and other devices on a large number of hardware and software resources and application services together, work together. Simply put, cloud computing is the different computers on the network to do one thing at the same time, significantly improve data processing speed.

1.2 Characteristics of cloud computing
Cloud computing is a distributed system, but with the traditional distributed systems and differentiated, it has the following characteristics:
1.2.1 ubiquitous network. Cloud computing is Internet-centric data storage and network computing service mode, the user and the link between cloud service providers to achieve through the network of cloud service providers will be idle through the standard procedures found in resources to focus on running around on the Internet, large-scale server clusters, the user only needs access to the Internet through any one of the terminal will be able to assign permissions to access and edit the data.

1.2.2 resources together, share common. The goal of cloud computing is the sharing of network resources, the use of cloud service providers on the network server cluster as a data storage center, archive resources, and software rental and leasing services to provide multi-tenancy model services.

1.2.3 Self-service cloud computing is the emergence of web services after a natural development, and continued the interactive features of web2.0, user access to the specified permissions, you can adjust according to demand and edit documents stored in the cloud.

1.2.4 rapid, mobile deployment of resources. Cloud computing system functions or demand can be rapid and flexible adjustment and distribution, the user, the cloud seems to be endless resources, ready to expand according to demand.

1.2.5 computing services. Cloud services resources can be used to control and supervision, and thus the effective deployment and optimization.

2 cloud computing in the domestic application of the library community colleges
2.1 University Library entry point for cloud computing applications
Library of basic social responsibility is the preservation, dissemination of the cultural heritage of human civilization and a variety of Information and knowledge resources to university libraries to meet the teachers and students is also charged with the task of education and research. With the development of digital libraries, Information resources, preservation, transmission has been a certain degree of resolve, digital library to break time and space constraints, the degree of Information sharing to achieve a high level, university libraries also organized a variety of alliances in order to share resources. but still faces some problems, such as Information Technology R & D personnel and a lack of new information technologies led to the library for the application of hysteresis, although the sharing of information resources to achieve a certain degree of development, but different data platforms, and docking between different systems is still difficult, and the high cost sharing and how the protection, respect for intellectual property rights under the premise of the maximum reduction in information acquisition and use of the threshold; how to maximize limited funding, to meet the target user's information needs, and so a range of issues.

With the "cloud" the continuous development of its outline has become clear in front of us, the cloud of available mass storage capacity, flexible access nodes, resources, access to convenient features such as, to achieve the joint between the university library catalog and resource sharing, to achieve one-stop integrated heterogeneous database searching, thus optimizing the use of funds, reduce the system's operation and maintenance costs, improve efficiency, improve the user experience to make college accessible to students and teachers access to more resources, to meet the various needs of university library users, including their potential needs in addition Cloud uses special low-cost fault tolerance measures available nodes cloud, through a centralized automated management, libraries without the burden of data center management costs, these will be responsible for cloud service providers, libraries need to share resources to the cloud.

Foreign university libraries use cloud computing earlier in China, the largest foreign operation of a successful project is OCLC's WorldCat database, it is also the library community's first attempt to cloud computing, currently more than 70,000 libraries around the world have joined The project, about half of the university library. The system can achieve a unified purchasing, cataloging, circulation management, and all services are available to libraries through the cloud, so that each library is no longer required to have their own set of plans integrated library system, do not even need your own server, and Internet access devices only need to complete a variety of routine library work. OCLC WorldCat Local provides a powerful search interface and cover the entire network of information retrieval services cloud Technology using simplified search process allows users to search through one-stop shop where one-time access to library collections, where the participating library's holdings and library consortia worldwide OCLC WorldCat union catalog of library data, access to table of contents, summary, Cover images and other information.

Currently the library has begun to take shape cloud service applications, such as CALIS distributed digital library building cloud services platform, opened the era of cloud university library, Superstar "Hundred chain" is in the cloud and cloud information Technology to achieve resource sharing and one-stop search through a variety of embedded tools such as literature analysis tools to simplify user operations and optimize the user experience.

3 cloud-based Library Information Service Innovation
In the cloud era, the focus of university library information services by the first hardware-centric to software-centric, service-oriented, fundamentally changed the traditional information retrieval, preservation and service concepts and methods, for the university library information services to create better conditions. Various colleges and universities to purchase access to the resources of the World Wide Web, the cloud service provider for unified management, maintenance, sharing, available to users through the cloud, which makes the service capacity of the various university libraries and the amount of resources to achieve unprecedented levels through the integration of library can only provide users with links to Internet devices, will be able to achieve service to readers, thus saving a lot of money in such a cloud era, Library Information Service do?
First, the librarian in the daily work experience, based on the distinction between popular literature and even less frequently used resources and almost no literature resources will be used to cloud storage, data can be stored on the one hand, the other to facilitate a wider audience readers, including other universities authorized to use the same resources simultaneously.

Second, the university library can be achieved using cloud computing for heterogeneous databases, the combined resources of different types of literature retrieval, allows the reader to retrieve all the available resources-time, and through literature and other tools to provide the necessary resources to gradually precise positioning.

In addition, full use of information technology such as blog, microblogging, etc. Today, web2.0 has become part of everyday life in April .2010 and even the Library of Congress since 2006, announced that all public twitter files into collections. network environment, information technology changing the way people use the Internet, and university libraries should adapt to this trend and even lead people to follow up with a variety of new ways to use the library for resources, so should rely on their own resources to university libraries The advantages of active use of information technology to enrich their transfer and exchange of information between the reader interaction channels into the reader's real life.

4. The issue of cloud computing
There is no doubt the potential of cloud computing, which change the development model, while both the library can bring many benefits, but there are some issues can not be ignored.

First, the use of integrated library systems, admin tools are different, the use of cloud computing services, had been disrupted workflow, integration with existing systems are successful, the need to modify the system to match the other, these are urgently needed problem and secondly, to provide cloud computing services of many Internet companies, using different standards and technologies, therefore, is compatible between the different cloud sharing of information resources directly affect the results. Third, the use of SaaS services, books Museum with the cloud service provider separation, control of the system or part of the loss, if there are problems, timely maintenance and repair is unknown. Fourth, the shared library if the cloud variety of database resources, internal documents, personnel data Readers of personal information and other content, data security and user privacy to be protected is to solve the problem. Finally, the cloud computing resources without sharing the same border, the biggest problem is how to protect intellectual property rights, how to define the scope of fair use how intellectual property rights, without prejudice to the premise of cloud for the university libraries realize the benefits.

5 Conclusion
Cloud computing era library, less thick book, but much better quality and light service. When technological progress, the library's existence not only to save the process and traces of human civilization, but also remind us should pay more attention to the needs of readers when the readers' demand for services has become unavoidable, the library should carefully consider new forms of service provision and application of cloud computing applications will become the most exciting new generation of library place. ◆
