Royal Society Corpus
The Royal Society Corpus (RSC) 6.0 Open is based on the first centuries of the Philosophical Transactions of the Royal Society of London from its beginning in 1665 to 1920. It includes all publications of the journal written in English and containing running text. The Philosophical Transactions was the first periodical of scientific writing in England. Founded in 1665 by Henry Oldenburg, the first secretary of the Royal Society, it initially contained excerpts of letters of his scientific correspondence, reviews and summaries of recently-published books, and accounts of observations and experiments.
