Current practices for transforming library legacy records into linked data for libraries were studied. The Linked Data Cookbook released by W3C was used as an analytical framework. A total of sixteen library linked data case studies focused on converting library catalogue data into linked open data were selected as subjects to analyze the details of transformation according to the following categories: identifying data, modeling data, naming with URIs, reusing existing terms, publishing human and machine readable descriptions, RDF conversion, license, download, host and announcement. It was found that although most tasks defined by the Linked Data Cookbook were adopted, some extensions and refinements were adopted to meet specific library-oriented requirements. Related issues including selection of data, selection of terms, 1-to-1 mapping principle and long-term preservation of library linked data are discussed.
