Local Knowledge, Part 4: Big Apple, Fine Print

Brooklyn directory dated August, 1941
had listings "corrected to July 10, 1941"
Read the fine print to date a source.

That's my local knowledge tip for today.

It actually works for every source in every location.

But in New York City, finding the date of a phone directory takes a bit more effort, because the entire city population is NOT listed in a single, massive directory. No, New York has five boroughs, each of which has its own quite large phone book.

Five boroughs, five phone books, and--just to make things more interesting--five different cutoff dates for listings. Which borough did your ancestor live in, and when? The fine print matters in the Big Apple.

August Cover Date Means . . . ?

In my previous post about searching free NYC telephone directories, I showed a sample from a 1941 Brooklyn phone directory. The snippet at top is a repeat because I want to emphasize that the cover date was August, 1941.

I clicked to the official page 1 of that directory to read the fine print. It said: "This issue corrected to July 10, 1941."

So what? If I search the August edition for an ancestor who moved to a new Brooklyn address on or after July 11, I either won't find that person or I'll find outdated information. A missing listing might mean . . . passed away, or married, or changed name, or moved away.

Or if someone's missing, it might mean no phone (ever or only for that particular year). That was the explanation when I couldn't find ancestors who, it turned out, were living as boarders in someone else's apartment. I discovered them in an earlier directory and in a later directory, both times in their own apartment.

Five Boroughs, Five Cut-off Dates for 1940

Looking at the 1940 phone directories digitized and posted online by the New York Public Library, I was surprised to see that each borough's directory had a different cut-off date for listings.
  • Manhattan (1940 directory): "This issue corrected to November 9, 1939."
  • Bronx (Winter 1939-40 directory): "This issue corrected to October 19, 1939."
  • Brooklyn (Winter 1939-40 directory): "This issue corrected to January 4, 1940." 
  • Queens (Winter 1939-40 directory): "This issue corrected to December 13, 1939." 
  • Staten Island (Winter 1939-40 directory): This issue corrected to January 9, 1940."
I had ancestors in four of these five boroughs, so I needed to know where to look and check the dates of each edition. "New York City, 1940" wasn't enough.
