Radium annotated bibliography compiled in 1903 in the USA

References compiled in the USA (as distinct from Europe) for the years to 1903 are contained in this bibliography. The summaries provide an interesting insight into the opinions and knowledge on radium which were held in the USA during the first few years after its discovery in 1898. The compiler of these references was almost certainly a profesor of chemistry and mineralogist, Charles Baskerville (1872–1922) of New York. Some references are from academic scientific journals whereas others are from the popular scientific press. In these early years following the discovery of radium, publications and commentaries on them were far more in Europe than in the United States. This scientific fact gives some importance to this bibliography. I have retained the original spelling and punctuation used by Baskerville.
