Abstract: As an important institution for content storage, acquisition and dissemination, university library
breaks through the traditional knowledge service system and comprehensively supports the needs of the
new liberal arts for cross-linguistic and interdisciplinary communication. Library is bound to be required
to strengthen discipline cooperation and integration with the help of information technology, to expand the
connotation of discipline service, and to build a data service model dominated by scientific research data
management, development and service. The library service mode is inseparable from the support of five
elements: resources, space, librarians, service, and platform. This paper closely connects the changes of five
elements under the background of new liberal arts, introduces the concept of data center into the construction
of library service system, reconstructs the “five in one” data service mode of university library in the future,
and demonstrates it through specific construction and service practice cases. Focusing on the concepts of
“resources +”, “space +”, and “librarian +”, the library of Shanghai International Studies University constructs
a data middle platform with resources, digital tools and algorithms as the main body, and is committed to
creating a digital academic environment that integrates multilingual Digital Resource Center, Digital
Humanities and academic laboratory, digital content creation and creativity space, and wisdom sharing and
discussion space. While improving the interdisciplinary support and service ability of the library, it promotes
the formation of data thinking of teachers and students, so as to comprehensively help the interdisciplinary
integration and collaborative innovation of the school under the background of the new liberal arts.
