Data Science & Metadata Research

To be discoverable by today’s online users, traditional library data must be transformed. OCLC Research analyzes bibliographic data to derive new meaning, insights, and services for use by library and information seekers. This work includes special projects, data science research, engagement with metadata communities, publications and presentations, and the creation of illustrative experimental applications.


Some of our research is manifested in experimental applications. Please note that these are for demonstration and illustrative purposes only. If something isn’t working, or you’d like to share your feedback, please let us know



ArchiveGrid is a growing collection of over two million archival material descriptions that provides a foundation for OCLC Research collaboration and interactions with the archival community, and also serves as the basis for our experimentation and testing in text mining, data analysis, and discovery system applications and interfaces.
