As Big Data has emerged as the basis of modern research, fittingly it has also become apparent in research libraries. Data centers equipped with data librarians are becoming more prevalent. Information professionals serve as stewards of access and instruction to information resources, the tidal wave of datasets is no exception. Data librarians have emerged as specialists on data resources, tools and also data management plans that are required for research grant proposals. With more publicly accessible datasets from government funded research, privacy ethics can fall on scientists and funding agencies. Librarians are poised, and in some cases required, to be part of the data revolution. Despite the specialty area of data librarianship, the information profession field should be aware of growing data-based research and the issues involved.
