Grass-roots historical research

Via 3QD, an interesting essay on crowd-sourcing in historical research. It seems not to have yielded a signature finding—in the way that much of political reporting has—but the possibilities are pretty interesting:

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.
