Just to let you know....not only can you pick up schedules of readings at local bookstores but you can also find them on the web.
see the following links:
Barnes and Noble
**Upstairs at the square events at barnes and noble in union square
click my stores, put in a zip code and then the events show up and you can even select "see more events" on any location that shows up.
I think the web is more utilized than going to the book stores themselves and picking up a monthly calendar event schedule. But now you see there are an abundance of events.
