The Great Neck Public Library on Long Island recently digitized its microfilm reels of the Nassau Alphabetical New York City Telephone Directories (Nassau County) and has put this database on the library website.
The library owns 25 rolls of microfilm which covers the years 1913-1974. The microfilm includes both the white pages and yellow pages. Early telephone books are organized alphabetically by community and then alphabetically by surname. Though the directories are for Nassau County, a few towns from western Suffolk County, such as Huntington and Amityville, may appear in some directories.
When a search of the database is done, the word you searched on will be highlighted in the results.
There are plans to add more directories to the database, eventually adding directories up to 1990.
