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 found in journals/books available in libraries or via interlibrary loan. There are also a few less accessible items cited that were 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. Barbara Fleisher Zucker
