I mentioned the other day that the last in the New York: A Documentary Film series, "New York: The Center of the World," has a website on which you can find the transcript of the broadcast, as well as other helpful features. You can also access descriptions of the other episodes, but there are no transcripts. Nonetheless, it might be worth your time to look at the Big Apple history section...it certainly won't hurt. Click here to go there(if that makes any sense).
If you scroll down this page, you will find a great site for the Triangle Shirtwaist fire, which is the subject of one of the two questions in part II.
Onward and upward, as my grad advisers used to say!
