Samuel C. Bradford

Samuel Clement Bradford was a British mathematician, librarian and documentalist at the Science Museum in London. He developed "Bradford's law" regarding differences in demand for scientific journals. This work influences bibliometrics and citation analysis of scientific publications. Bradford founded the British Society for International Bibliography and he was elected president of International Federation for Information and Documentation in 1945. Bradford was a strong proponent of Universal Decimal Classification and of establishing abstracts of the scientific literature.
He became head of the Science Library in 1925 and became Keeper of the Science Library in 1930. He was succeeded in this role by Ernest Lancaster-Jones in 1935.
