What does 140,000 documents look like? See below!

Let's start with a smaller number - 1,000.

Imagine going through 1,000 historical documents and cataloging them - determining the date, who wrote the document, who it may have been sent to, what the document is about... that's what our editors do!

Now let's look at a much larger number - 47,000. Can you imagine it? Maybe this will help.

That's right - there are 47,000 buildings in Manhattan. Our collection is 3 times the size of that!
