The History of Science Museum contains an internationally important collection of scientific objects, but only about one fifth of the collection is on permanent public display.
Regular Special Exhibitions often showcase objects normally in store. The Collections database contains detailed information on over 30,000 objects, manuscripts, and other archives, many of them photographed. Members of the public can, where appropriate, make research visits to view objects.
