Okay thank you all for joining us this evening tonight on the very eve of the children 50th anniversary of the boston massacre we will hear from professor serena with a great new book the boston massacre, Family History. As a regular guest notes we pull together small exhibition from our collection that highlights the material we have within our holdings that eliminates the discussion today we have an entire exhibition. We did not need a small exhibition this time. That only to have a small exhibition bar exhibition actually features our speaker this evening.
