Abstract: 【Purpose/significance】The purpose of maturity evaluation of library data governance is to measure the strength of library
data governance ability, which has a guiding role in promoting the implementation process of library data governance and improving
the defects in library data governance.【Method/process】Based on the analysis of the existing research on the elements of data gover⁃
nance, this paper puts forward the elements model of library data governance. Based on this, combined with the industry particularity
and Capability Maturity Model of library data governance, this paper constructs the capability maturity model of library data gover⁃
nance from two macro dimensions of data processing process and elements of library data governance, and establishes the evaluation
system of library data governance.【Result/conclusion】The proposed maturity evaluation model of library data governance provides a
tool to judge the maturity level of library data governance ability, which can reflect the specific implementation effect of library data
governance, quickly locate its weak links, and accordingly put forward targeted promotion and improvement strategies. 【Innovation/limi⁃
tation】This paper builds a library data governance maturity evaluation system based on the CMM model, combining data processing
procedures and library data governance components. However, due to the limited number of libraries that carry out data management
at present, it is impossible to compare the differences in data management capabilities between different libraries in a more comprehen⁃
sive manner.
