The National Science Library (NSL), formerly known as the Canada Institute for Scientific and Technical Information or CISTI, began in 1917 as the library of the National Research Council of Canada (NRC). NRC is the Government of Canada's premier research and technology organization (RTO), working with clients and partners to provide innovation support, strategic research, scientific and technical services. The library took on the role of national science library unofficially in 1957 and became the official National Science Library in 1966.[1]
