BROOKLYN - The Historic Archive Collection at the 177-year-old Green-Wood Cemetery is set to go digital.

It's a massive undertaking involving the records of around 570,000 people buried at the cemetery, according to Lisa Alpert. 

The physical records fill two rooms from top to bottom. They include millions of items altogether, because each person has a series of additional documents and records related to the burial, Alpert says.

Some examples include an invitation to the opening of the Brooklyn Bridge, a photograph of Mark Twain and a check from the infamous Boss Tweed.

"We have just under 8,000 collected objects, which include photographs and letters documents," Alpert says.

The oldest records date back to 1838. Experts say scanning them into a digital format will not damage the originals.

The digitizations plan will be completed by April 2017.
