The National Archives is brimming with historical documents written in cursive, including some that date back more than 200 years. But these texts can be difficult to read and understand— particularly for Americans who never learned cursive in school.

Reading cursive is a superpower,” Suzanne Isaacs, a community manager with the National Archives Catalog in Washington, DC, told USA TODAY.

The National Archives needs help from people with a special set of skills–reading cursive. The archival bureau is seeking volunteer citizen archivists to help them classify and/or transcribe more than 200 years worth of hand-written historical documents. Most of these are from the Revolutionary War-era, known for looped and flowing penmanship .

Or a few million. More than 200 years worth of U.S. documents need transcribing (or at least classifying) and the vast majority from the Revolutionary War era are handwritten in cursive – requiring people who know the flowing, looped form of penmanship.

The National Archives is looking for volunteers to transcribe more than 200 years worth of documents written in cursive.
