Just wanted to give wikinomics readers a heads up that a little over a week ago Stephen Mihm had a great article in the Boston Globe called Everyone is a historian now. To quote the opening:

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.

It goes on from there, and one of the underlying themes is how easy enabling the collaborative process is – and how much better it makes our collective historic record. To quote again:

Late last year, the Library of Congress posted several thousand of its photographs on Flickr and asked the public for help: What is this? Who is this? When was it taken? Curator Helena Zinkham, who oversaw the program, was stunned to discover how quickly the gaps were filled by amateur enthusiasts – and in some cases, people with firsthand recollections.

This was particularly the case where the images attracted the attention of a particular group of enthusiasts: military aviation buffs, for example, or aficionados of early baseball. One collection depicted early-20th-century boxers, many without vital information – perhaps just a last name, like “Wells.”

“By the time the conversation was done,” Zinkham says, “we were able to tell Matt Wells from Bombardier Billy Wells.”

Other great examples are presented from there – it is well worth your time.
