Stephen Mihm: Everyone's a historian now

[Stephen Mihm is a history professor at the University of Georgia and author of "A Nation of Counterfeiters" (Harvard, 2008)]

UNTIL RECENTLY, IF you were a historian and you wanted to write a fresh account of, say, the Battle of Leyte Gulf in World War II, research was a pretty straightforward business. You would pack your bags and head to the National Archives, and spend months looking for something new in the official combat reports.

Today, however, you might first do something very different: Get online and pull up any of the unofficial websites of the ships that participated in the battle - the USS Pennsylvania, for example, or the USS Washington. Lovingly maintained by former crew members and their descendants, these sites are sprawling, loosely organized repositories of photographs, personal recollections, transcribed log books, and miniature biographies of virtually every person who served on board the ship. Some of these sites even include contact information for surviving crew members and their relatives - perfect for tracking down new diaries, photographs, and letters.

Online gathering spots like these represent a potentially radical change to historical research, a craft that has changed little for decades, if not centuries. By aggregating the grass-roots knowledge and recollections of hundreds, even thousands of people, "crowdsourcing," as it's increasingly called, may transform a discipline that has long been defined and limited by the labors of a single historian toiling in the dusty archives.

Some venerable research institutions are already starting to harness the power of crowds in an organized way. The Library of Congress recently launched a project on the photo-sharing site Flickr that invites visitors to identify and analyze photographs in its collection, while the National Archives, working in partnership with a for-profit company, is inviting people to do the same to online versions of its documents. And a growing number of projects are taking the logical next step, creating "raw archives" of photographs and documents for momentous events: Sept. 11, for example, or Hurricane Katrina.

"When a historian writes about a particular period of American history, he has a few hundred pages to do so, and things inevitably get left out," says Daniel Cohen, director of the Center for History and New Media at George Mason University. Projects that employ crowds of researchers and writers, he says, "allow for a wider array of details and perspectives that a single master narrative doesn't allow."

So far, only a handful of professional historians have begun to exploit crowdsourcing, which remains a relatively crude tool for gathering and organizing knowledge. But as the power of crowds meets the practice of history, these online repositories represent a remarkable change not only in how historical materials are gathered and organized, but, perhaps most important, in how deeply and broadly the past can be understood....
