Roger,
The 'Research Area' never is 'open' as such. And asking one of the
docents probably won't get you anywhere, either. If you go to the
'office' {actually off the Seaport 'grounds'} and state you purpose . .
.. most likely they will be able to help you. Similarly, if you contact
the 'Research Department' {?} via the 'general' web-site link, they do
respond.{just found a direct address - }
