Kronos, published from 1980 to 2001, is the yearbook of the School of Medicine at Stony Brook University. Stony Brook University Libraries has digitized every issue of the yearbook to expand access to them and to preserve an important source of university history. The Kronos Digital Yearbook Collection provides online, searchable access to the issues through a webpage interface. Original copies of the yearbooks are housed in the University Archives and in the Health Sciences Library.

Stony Brook University’s School of Medicine opened in fall 1971. The inaugural class of 17 medical doctors graduated in 1974. The first issue of Kronos was published in 1980, the same year that Stony Brook University Hospital opened its doors and became the region’s first academic medical center. The schools comprising the health sciences and the hospital were founded in response to a report commissioned by New York State Governor Nelson Rockefeller in 1963. The School of Medicine was renamed the Renaissance School of Medicine at Stony Brook University on November 21, 2018.
