The Scientific Instrument Society’s 25th Anniversary Exhibition is currently on exhibit at the Museum of the History of Science until 26 September 2008. It is a loan exhibition from members of the SIS of 50 items from 20 private collectors. The web version of the exhibition contains images of all the items plus the descriptions written by the collectors and the exhibits two curators.
Also, while writing about the Museum, I wanted to mention that the beta version of the new online catalogue is online with nearly 17,000 objecs catalogued. It is much better than the old version and so far, in my use of it, has not once returned an error (like the old one used to).
