Libraries as a type of social institution have a long history of collecting, preserving and spreading the knowledge of mankind and have cumulated a vast amount of highly structured data conforming to library and information standards. Among these data, especially, name authority data are fundamentally important for digital humanities. However, traditional library data are not built in the way that digital humanities research requires, which makes it difficult for digital humanities researchers to use them directly. This study is to address this problem through using the Linked Data approach to build knowledge bases in transforming and normalizing name authority data into the format that can be easily deployed by digital humanities research. A name authority database was built on various sources and formed the content infrastructure to provide Linked Open Data services, which enables sophisticated searches and uses of document resources knowledge base with multiple types of documents and multimedia, instead of digital collections with only a keyword search function. The process of design and development as well as the way through which resources are interlinked are described in detail in this paper.
