DNA testing may unlock secrets of medieval manuscripts

Taking advantage of the fact that many medieval manuscripts were written onto animal skins, scientists are using the remaining DNA from these skins to help identify manuscripts that were created near one another in time and space.

From the original article:

"Thousands of painstakingly handwritten books produced in medieval Europe still exist today, but scholars have long struggled with questions about when and where the majority of these works originated. Now a researcher from North Carolina State University is using modern advances in genetics to develop techniques that will shed light on the origins of these important cultural artifacts."
