I have invested in some good books for writers on the New York Theatre scene: The Dramatists Guild Resource Directory, Dramatists Sourcebook and the most recently published Theatre World, which have all proved to be very useful. It is only when you are trying to make connections in another city that you realise how much you know about your own. Just checking things out on the internet is just not enough.
After going to Delaware I am going to be staying in New York between 16th November and 21st in a lovely little brownstone hotel in Chelsea. I found it in The Dramatists Guild book, which has a couple of pages of reasonable hotel suggestions along with all the usual stuff about theatres, agents and producers.
