Here is a peek at some of the treasures in the Pennsylvania archives:

The oldest record is a 1664 series of "articles" that outline the privileges of the Dutch after the English takeover of the Mid-Atlantic region.

Pennsylvania is the only state to have a file of Civil War conscientious objector depositions.

There are 7.5 million birth and death records open to the public, deaths from 1906 to 1963 and births from 1906 to 1908.

There are 1 million photos.

There is one of only two known film clips showing President Franklin Delano Roosevelt, who was stricken with polio as a young man, walking. The clip was featured in the Ken Burns PBS series The Roosevelts.
