If you want a section of a map showing the location of a certain address within New York City, you can go to http://gis.nyc.gov/doitt/nycitymap/ All you have to do is type in an address and you will see a small section of the city map with a red box indicating the building you are searching for.  I have found this invaluable in finding my family in the 1940 census, because now I have the cross streets which will enable me to get the correct ED. Hope this is useful to you. Bill Hinkle Port Orange, Florida
