[Purpose/significance] Discussion on the evolution of library data forms is helpful to understand research emphases on library data in various forms, as well as the future research direction.[Method/process] Based on investigations on four OCLC data science projects and three forms of data representation reflected in them, forms of library data are divided into five types, including original data form, aggregation form, extended data form, linked data form and knowledge form.[Result/conclusion] The processing depth and breadth of library data is gradually strengthened with its form evolution. The orderly evolution between these forms can be achieved through multi-source polymerization, internal generation and external association, converting library data into linked data, extraction and fusion of knowledge triples.
