The Yangtze River Repository is a characteristic database subsidized by CALIS and is co-constructed by Wuhan University Library, the Library of Yangtze River Water Resources Commission and Wuhan National Science Library of the Chinese Academy of Sciences. It provides information retrieval and other services for those managers, educators and technicians from the local area, the entire nation as well as the whole world who are engaged in research about the Yangtze River basin, so as to propel resources utilization of the Yangtze River basin and its economic development, to promote the exchange and improvement of scientific research, and to make it become gradually the base for the construction and application of information resources of the Yangtze River. The Yangtze River is the third longest river in the world and the longest one in China. It is the cradle of Chinese civilization and the most vital artery of contemporary China’s economic and social development. The Yangtze River Repository is the biggest information repository in the Yangtze River basin in China. To meet readers’ demands, books, periodical articles, dissertations, conference articles, technical reports, newspaper articles, internet resources, images, audio-visual as well as other resources are extensively collected. There is another selection of indexes, abstracts, full texts and knowledge units. Subjects covered by the database are classified into the sectors of the river basin, the environmental protection, the water conservancy, the economy, the tourism, the culture, and the encyclopedia, etc. of the Yangtze River. Different databases of books, theses, news, internet resource, images, multimedia, bibliography and knowledge are established according to the reference types. Inquiry is provided according to the thematic types such as policy, low-carbon economy, water conservancy, water resources management, shipping port, ecology, urban economic circle and basin planning of the Yangtze River. The database has 250,000 records already and keeps gradually updating. The Yangtze River Repository is free and open to all users, while full text information requires limited use. The repository also provides interactive information service, such as document delivery service, expert consulting and custom service. Moreover, there are related links to the CALIS Center, CALIS Thematic Special database and other resources.

This database is based on the featured database of China Hydraulic and Hydroelectric Engineering. It extends to the collection, arrangement, preservation and distribution of relevant data about Chinese large and medium-sized hydroelectric engineering project along the history such as Dujiangyan, Beijing-Hangzhou Grand Canal, Jingjiang Flood Diversion, South-to-North Water Diversion Project, covering hydroelectric engineering, irrigation and drainage, river basin management, flood control and reduction, river channel treatment, embankment construction and utilization of water resources.

Major construction contents of the database:
• Abstracts databases of Chinese hydroelectric engineering periodicals: based on the periodical holdings of Wuhan University Library, and back to the founding volume of the related journals.
• Full-text electronic database: It provides retrospective database construction for the books mainly related to hydraulic engineering (including hydrological almanacs, etc.), among which hydrological almanacs are open to on-campus readers only.
• Historical materials of Chinese Hydraulic and Hydro-Power Engineering: Post-1949 historical materials of engineering take the major part.
• General introduction to large and medium-sized water Hydraulic and Hydro-Power Engineering.
• Database of Chinese large and mediumsized hydraulic engineering on the basis of digital maps.

Database of China Hydroelectric Engineering provides visualized search of maps with MapInfo. Readers can achieve information search of power plants with the help of digital maps, and the retrieval of the subdatabase of TPI system is made by MapInfo system through the opened URL. The visualized search is well integrated with the traditional search by the outside system retrieval method. This provides more comprehensive and convenient information retrieval service for users.

“Luojia Model Mien – Database of Wuhan University Masters” originates from joint CALIS (China Academic Library & Information System) program by Wuhan University Library and Wuhan University Archive. The database mainly collects related documents of influential Wuhan University masters in different periods of the history of the university, to highlight the scholarly model mien of Loujia masters, to inherit the teachings of the masters, and to straighten out the cultural lineage of Wuhan University, as well as to propagate the academic spirit of the university. According to CALIS criteria for recommending masters and the actual situation of Wuhan University, the first list of 171 masters has been launched into the database, including academicians of Central Research Institute (during the Period of the Republic of China), famous scholars who taught in the university before 1949, professors of the first, second and third national levels appointed in 1956, academicians of Chinese Academy of Sciences, academicians of Chinese Academy of Engineering, senior professors of humanities, and national distinguished teachers from Wuhan University. However, there are still 14 qualified masters not issued in the database for lack of sufficient data.

With a collection of about 71,000 kinds of books in western languages in CADAL project (University Digital Library International Cooperation Project), this database is a joint effort made by Wuhan University Library and other CADAL member libraries, most of which are pre-1964 social science works, covering politics, economy, military, nationality, religion, literature, science and technology, folklore, education and geography. Retrieval and full-text browsing can be achieved through the title, author, keywords, and publishing houses.

The National Institute of Surveying and Mapping Science and Technology Information plays a leading role in constructing this database with the participation of Wuhan University Library. It contains 73,129 records, sources of which are from domestic and foreign journals of surveying and mapping or related subjects (over 100 kinds), conference proceedings, reports and monographs.

Based on ESI, SCIE, SSCI, A&HCI and subject classification system of journal partition system under SCI of CAS (Chinese Academy of Sciences), this system offers general guidelines to highly influential international journals, and integrates systematically journal information from different databases or evaluation systems, providing one-stop information about submission guidelines of SCIE, SSCI, A&HCI journals, including impact factor, journal partition, journal introduction, submission guidelines, editorial board information. It helps readers to get acquainted with the comparative importance of different journals in various fields and provides reference for them to make a proper choice of submission.

This database contains over 100,000 Master’s & Doctoral dissertations since 1964. Through retrieving the author, title, major, keywords or superviser, on-campus network users can view the abstract and the first 16 pages of each dissertation. Full- text online browsing is also available. Other users can retrieve and view the basic information such as the abstract by anonymous login.

The paper dissertations are collected in the reading rooms of every library. Dissertations from arts &sciences division since 2002 are mainly collected in the reading area B3 of the General Library. Electronic reading rooms of the Engineering Branch Library (second floor) store mainly dissertations from engineering division since 1998. Periodical rooms (third floor) of the Information Technology Branch Library mainly hold dissertations from information technology division since 1986. Dissertations from medical division since 1999 are collected in the compact book storage area and the lending and reading area of teaching reference books in the Medical Branch Library.
