Yale University Library offers extraordinary collections, spaces, technology, and research expertise. Some fifteen million print and electronic volumes are held at a dozen libraries and locations, including Sterling Memorial Library, Beinecke Rare Book and Manuscript Library, Marx Science and Social Science Library, and the Anne T. and Robert M. Bass Library. Yale Library Special Collections represent the diversity of the human experience in forms ranging from ancient papyri to early printed books, rare film and music recordings, and born-digital materials. Through rapidly expanding digital collections, online resources, and an array of tools and services, the library supports data-intensive research and is advancing the ethical, effective use of artificial intelligence in research. About five hundred staff facilitate teaching, research, and practice with deep subject knowledge as well as expertise in digital humanities, geospatial analysis, computational methods, and statistical support. Library preservation and conservation specialists employ leading-edge technology to maintain collections, supporting increased access, a vibrant exhibition program, and the university’s emphasis on teaching with primary sources.
