The screen was purchased by the Museum from Chang Chung-Ti of Beverly Hills, California in 1966. Joseph Needham and Lu Gwei-Djen then published a paper on the screen. The paper was subsequently revised and included as a chapter of 'Hall of Heavenly Records: Korean Astronomical Instruments and Clocks, 1380-1780', (Cambridge University Press, 1986).

The Portsmouth Collection is the principal collection of Isaac Newton's scientific and mathematical papers, including early drafts of the Principia, and his correspondence with Oldenburg, Halley Flamsteed and many of the other most prominent scientists of his day.

Includes information regarding salaries of members and imprest monies, financial reports and correspondence with the Admiralty.

The archives comprise the records of internal governance, finance, building and equipment development and astronomical observation, together with several small assortments of personal papers of individuals associated with the University Observatory, its sister and successor bodies, such as G.B. Airy, H.F. Newall and R.O. Redman.

MS copy of an astronomical treatise, containing a drawing and description of a quadrant or sextant for measuring angles by reflexion.

Observations from Captain Cook's last voyage.

The Macclesfield Collection principally comprises the archives of John Collins (1625-1683) and William Jones (1675-1749). As well as being mathematicians in their own right, both men corresponded with leading scientific figures of their day and so the collection includes autograph material by Isaac Newton, Edmond Halley, Henry Briggs, Roger Cotes, Henry Oldenburg and Robert Hooke.

Astronomical notes, communications, observations and tables received from Flamsteed, Halley, de Louville, Pound and others, in various hands, including some notes in Newton's hand.

The items include the astronomical observations of Willem Barents, 1596-1597; a comparative table of thermometer scales; and a list of flora.

Pressland, 89 folios: (fo. 1) the Russian Academy sketch; (fo. 46) lecture by A. M. Liapunov 'On the form of celestial bodies'; (fo. 77) obituary notice for Liapounov. Contributors include A. J. Pressland.

Captain Cook's journal of his voyage to the South Seas, including observations of variation of the compass and observations for chronometer rates.

This series comprises publications of meteorological data and of catalogues of observations of the stars and planets obtained with the Carlsberg Automatic Meridian Circle (CAMC). The publications were produced by the Real Instituto y Observatorio de la Armada en San Fernando, Copenhagen University Observatory and Institute of Astronomy, Cambridge, and latterly, solely by ROA.

A series of booklets containing measurements of the meteorological conditions, astronomical seeing and atmospheric extinction made at the site of the Carlsberg Automatic Meridian Circle (CAMC) in the Observatorio del Roque de los Muchachos, La Palma, Islas Canarias.

A set of catalogues of observations of positions of stars and planets, obtained with the Carlsberg Automatic Meridian Circle on La Palma.
