"Microfilm copies of the papers of John Flamsteed, Astronomer Royal 1675-1719. Flamsteed's observations, made with the various instruments that he acquired, are preserved both in their original note books and in the form in which he eventually put them together to be published posthumously in his Historiae Coelestis of 1725 and his Atlas Coelestis of 1729. There is also correspondence with contemporaries including Isaac Newton, James Gregory, Edmond Halley, Johannes Hevelius and Giovanni Domenico Cassini as well as amateur astronomers. The collection also contains correspondence and documents involving aspects of Flamsteed's life outside astronomy: as rector of the parish of Burstow and as the inheritor of his father's lead mining interests."@en . .
