In academic libraries, the area of data librarianship has introduced several new functions and skills into the librarian toolbox. These include statistical and software support, research data management, data curation, and data and statistical literacy. Fostering data-related collaborations enables librarians to enhance library services, collections, and outreach. In this chapter, we will focus on academic library collaborations with government agencies as case in point. Under the umbrella of open access, local and national governments have started making available the raw data that they collect, in the course of providing public services, for users to conduct their own analysis. This chapter will 1) describe data librarianship in academic libraries; 2) review open government data repositories; 3) outline concerns with open government data, such as metadata and data literacy; and 4) describe collaborative efforts between an academic library and New York City government agencies to address concerns with open government data.
