Hi,
There is an entry for the Science Museum in my book Children's Museums, Zoos,
and Discovery Rooms: An International Reference Guide (New York: Greenwood
Press, 1987), pp 27-28. At the end of the entry are citations to several
articles or references to the Children's Gallery to books. These sources
would be avialable via interlibrary loan. This citiation also includes a few
less accessible items provided by the museum at the time I was working on the
book.
Their Children's Gallery opened in December 1931 and was supplemented by
Launch Pad in 1986.
