What does the Adler collect?
The Webster Institute for the History of Astronomy cares for, studies, and interprets the Adler’s collections. The Adler boasts one of the largest and most significant collections of historic scientific instruments in the world. In addition, the collections include rare and modern books, works on paper, photography, paintings, models, and archives.
The Adler’s archival collections relate primarily to the 19th and 20th centuries, and contain manuscripts and printed materials. Strengths include the Adler Planetarium Institutional Records, the Derek J. de Solla Price Papers, the Roderick and Marjorie Webster Papers, and the Alvan Clark & Sons Business and Family Papers.
The Adler’s library collections include rare books, modern books, and periodicals. These materials cover a wide range of topics on the history of astronomy and historic scientific instruments. Rare book collection strengths include celestial atlases, books on comets, early works on instruments, and astronomical and cosmological texts.
The museum collections include works on paper, paintings, and three-dimensional objects. The three-dimensional objects include historic scientific instruments and astronomical models from the 12th through the 20th centuries. Strengths include astrolabes, sundials, and telescopes. The works on paper collection includes individual maps, prints, and bookplates. Strengths include comet and eclipse broadsides, portrait prints, and celestial charts.
Featured Project: Sundials Conservation

The Webster Institute recently completed a sundials conservation project. A conservator treated 85 sundials threatened by metal oxidation of silver, brass, and steel surfaces and by physical instabilities. These objects, largely made by European artisans from the 16th through 19th centuries, were distributed over six sundial types: garden and portable horizontal, string-gnomon, compass, Augsburg-type, cube, and diptych and triptych.
This project was supported by the Institute of Museum and Library Services, the Bay & Paul Foundations, and the North American Sundial Society.
