Abstract 
This article describes the China Digital Library (CDL) and explains how to use the 
computer network in China. It also explores the advantages of the China library in 
establishing the CDL. Finally, it examines the future construction and development 
plans for the CDL. 
China is a large country that contains 5% of the world’s population. Along with the 
rapid development of the Internet worldwide, China has advanced her steps. The digital 
library has become a focal point in the high-tech world. At the same time, it is also a 
very important symbol with which to evaluate the basic facilities of information 
sciences in a country. The leaders in library fields have done a great deal to play 
important roles in realizing the China Digital Library (CDL). 
1. The Current Situation of the China’s Computer 
Network (CDL) 
China’s computer network usage has become more and more common in recent years. 
Five national networks have been opened (see Table 1).

Today, 200 universities and colleges in 8 regions in China are connected to these 
networks. According to calculations given by Chinese authorities, at the end of June, 
2000, the number of computers connected to Internet was about 6.5 million, and the 
number of users accessing the internet was about 16.9 million. Based on these estimates, 
the number of users accessing the Internet will reach 30 million1 in 2002. 
2. The Application of Computer Network in China 
Libraries 
The Document Digital Center of the China National Library (CNL) was established in 
March 1999. At the China National Library, which is the fifth largest public library in 
the world, the resources have been digitized in CD-Rom storage. By the end of 1999, a 
total of 30 million pages, or 150 thousand copies of books, could be read on the Internet. 
In addition, 600GB of databases, catalogues, titles, and full text are available on the 
Internet at the CNL.2 
The digital library set up jointly by the Liaoning Provincial Public Library and IBM 
supplies a large number of multi-medium databases with 10GB of full texts, pictures, 
films and TV. The contents include rare books, scenic images, cultural information, 
local documents, etc. Today, the Shanghai Public Library is creating a CD-Rom of rare 
books. 120 thousand copies out of total 170 thousand copies of rare books3 will be 
planned to make CD-Rom. In the near future, rare books will be read by computer 
screen. Since the 1980s, The Integrated Library Automatic System (ILAS), designed 
and run by the Cultural Ministry, has unit users of 280.4 
Many kinds of techniques are used to digitize the Chinese resources, for example: 1. 
Making a CD-Rom database by the traditional method of typing by hand, as the CD-
Rom database of People’s Daily 50 Year, etc. 2. Cooperating with some companies 
abroad. The Liaoning Provincial Public Library cooperated with IBM to protect the rare 
books with the modest techniques of encryption and digital photography. 3. Using 
scanners to input digital pictures. So far, many libraries in China have begun to order 
CD-Rom at home and abroad. It is very common to use CD-Rom databases in public 
libraries. For example, the Tianjin Library, being a city public library, collects many 
kinds of CD-Rom databases, such as: Academic Search Full text International published 
3 
 
by EBSCO; Full text of Academic Journals published by Qinghua University, which 
contains more than 5,000 kinds of subject journals; Copy Materials of Full Text By 
Renmin University, which collects all kinds of key social science journals; and the 
Complete Library in Four Divisions, a CD-Rom database that contains one full Chinese 
rare book. 
Encryption and scanning techniques have not been widely used in China. Therefore, the 
process of digitizing resources is very slow. We have a long way to go to compare with 
foreign countries. We must pay more attention to studying and developing the digital 
technique to meet the needs of users. The Share System Project on Document and 
Information Network, run by the Document and Information Center of the China 
Academy of Science, began in 1996 and was completed in 1998. Sharing documents 
and information from the Local Area Network, Metropolitan Area Network, and Wide 
Area Network has been realized. Since then, the network and resource construction of 
documents and information have been combined together and realized as the Hundred 
Units Network Project of China Academy of Science. Under such conditions, four 
regions and more than 100 institutes can be serviced with a catalog and information 
search, and remote access users can get requirements free of charge through 
CHINAPAC(China Packet-Switched Data Network) or the Public Telephone Network. 
In Oct. 1997, The China National Public Library realized 2M connections with the 
China Public Computer Network and access to the Internet. In February 1999, the 
Library Area Network with 1000MB was put into use. The jointed point of Library Area 
Network is up to 2913. A 1000 M channel was put into use in March 2001 which is 
special for the China National Public Library. According to the calculation, more than 
ten projects on various digital libraries are being studied, such as the China 
Experimental Digital Library, the Intellectual Network-Digital Library System Project, 
mass storage and digital library application, etc. We can use these networks in various 
departments within China’s public libraries, for example, acquisition, catalog and 
classification, circulation, information search, inter-library loan, international libraries 
exchange activities, etc. 
3. Preparation for Establishing the CDL 
To catch up with the development of digital libraries worldwide, research work and 
development started in the mid-1990s in China. The concept of the digital library was 
introduced at the IFLA (International Federation of Library Association) Conference in 
1996, which was held in Peking, China. At the conference, IBM and Qinghua 
University demonstrated the IBM Digital Library Plan. In July 1997, the China 
Experiment Digital Library Project was reported to the China Planning Committee. Six 
public libraries participated in the project, including the China National Library and the 
Shanghai Library, among others. With this project, the CDL construction was officially 
4 
 
underway. The Digital Library Key Project-CDL Demonstration Project is a large 
cultural project in which many organizations in China participated. The project was 
begun in 1999. 
In October 1998, the China National Library Project was started by China’s Cultural 
Ministry and the China National Library, In March 1999, the National Library 
Document Digital Center was established, with over 30 million pages of resources 
scanned annually.5 In June of the same year, a CDL International Seminar was held in 
Beijing, China. At the same time, the network condition of CDL research work has 
reached the advanced level and technique has caught up with the international advanced 
Next Generation Internet (NGI) level. In this case, many research projects of the digital 
library began in China public libraries at provincial and municipal levels. The working 
meeting on the Library Project Resources Construction of China Digital Year was held 
at the end of 2000.6 The First Plan for the China CDL Project (2000-2005) was 
discussed and worked out at the meeting and also determined to process the resources 
according to the international standards concerned. Digital library research institutes 
have been established in some universities such as the Beijing University and the 
Normal University in the Northwest China.7 At the beginning of the 21st century, a new 
upsurge of research and construction of the digital library has started. From this we can 
see that the digital library research and construction work has developed so fast both in 
public and university libraries in China. 
4. The Advantages of the China’s Public Libraries in 
Establishing the CDL. 
First of all, a library contains rich documents and information, which are important 
national resources. The levels of storage, collection, development and use of document 
and information resources of a country is the important symbol showing a country’s 
cultural history, intellectual storage ability, and science and technology capacity. As 
one of China’s largest social information systems, the information resources of a library 
have an important position that cannot be replaced in quantity or quality. After many 
years of development, several large library systems have been established in China: 
public libraries, school and university libraries, and special libraries. Each has its own 
characteristics in information construction but can work together. The China National 
Public Library has been engaged in establishing the largest Chinese information base. 
So far, several Chinese multi-media information resource databases, like “Poems,” 
“China’s Ancient architecture,” “Marine Life,” “Universe Structure,” etc., have been 
completed. 
Cross retrieval can be done through five successive resource databases. That is, you can 
access related databases from required resource databases very easily and conveniently 
to get the information needed. Besides this, some local public digital libraries have been 
5 
 
established, such as the Shanghai Digital Library, in which the construction project 
contains the Shanghai picture dictionary, Shanghai cultural dictionary, rare books, 
Chinese newspapers and magazines, foreign language journal catalogs, etc. 
Started in July 1999, the China Experimental Digital Library Project was completed in 
December 1999. The libraries participated the project have since set up their own digital 
libraries: Beijing University digital Library, Qinghua University Digital Library, 
Liaoning Provincial Digital Library (public library), Shanghai Digital Library (public 
library), and Tianjin Digital Library (public library). Some of each library’s resources 
have been digitized, and we can read their special collections online. The CDL network 
will give us a wide concept of China’s library that mainly supplies information and 
resources in Chinese. It can provide the services of reading, retrieval, and researching 
documents of special subjects online to the public. 
Now, the top design of CDL Project--China Cultural Information Network--has been 
started. As calculated by the system of public libraries, at the end of 1999, the total 
quantity of documents in public libraries is up to 390 million copies, including large 
amount of rare books, local documents, nationality documents, special collection 
documents worthy of valuable research, etc.8 These documents are distributed all over 
China. They are the social information system with the greatest quantity and used 
widely, which can be served to the people directly. The problem is how to develop them 
and use them through a network. From this, we can see clearly that the library is the one 
of the most important organizations needed to realize network services. 
5. The General Purpose and Development Plan of the CDL 
Project 
The Digital Library Project in China has just begun. It is in an embryonic form that 
displays the library’s transformation from a traditional library to a digital library, which 
gives us a hybrid library today. We know very clearly that to establish a real CDL, we 
have a lot of work to do. CDL is a large project across areas, across departments, across 
professions. It is also a newly created high-tech project. 
High quality Chinese Digital Resources Databases Groups have been developed and are 
servicing China as well as the world through China Key Communication Network 
access to the internet. The techniques online in China have already been close to the 
international advanced techniques. 
The Project Target: 
More than ten databases of Chinese digital resources with a total capacity of not less 
than 20TB will be completed by 2005.9 At the same time, we will purchase many 
6 
 
special databases abroad and realize online acquisition and classification, as well as 
inter-library loan in most parts of China. The digital library application system with 
Chinese distinctive features will be completed. Many high level professional specialists 
will be trained to continue the development of the CDL Project. 
The Resource Construction of the Project: 
The resources Construction of the project include many fields, such as digital resource 
construction, system development, standards and specifications, and personnel training. 
We will develop a large number of Chinese multi-media digital resources databases 
with a total capacity of over 20 TB in the fields of culture, science and technology, and 
education.10 
The Project Feature: 
The feature of the project is the virtual network, which is a large-scale, open, and 
disseminated digital information resources network system structure. It has many 
functions, for example: complicated information process and access; mass capacity 
information development and memory; Besides Chinese language, there are many other 
languages online including information resources on foreign languages and nationality 
languages; the network system with compatibility, good inter-operation, open 
distribution, etc. All the work we have done must meet the international standards and 
specifications. CDL research in China started late as compared with developed 
countries. To realize the real digital library, there are many inhibiting factors, both 
technical and non-technical. The technical factors that restrict the realization of the 
digital library include: 1. A very large amount of information to be digitized. 2. Without 
the unified agreements, specifications and standards. 3. The construction of a network 
infrastructure. 4. Safety problem of a digital library and copyright questions. The non-
technical factors are questions of economy, management, and personnel. We need some 
time to solve all these problems, which are the same throughout the world. China, with 
its rich culture of 5000 years, is one of the largest countries in the world. We have the 
duty to do our best to share our information resources with the world and make the 
world we live in smaller and smaller.
