From John Hennessy:
As any of you who have the historical hound dog’s desire to hunt know, the world of online research is expanding before our eyes. It’s an exciting time in some ways, as the source material available to us grows every day. I confess I have reveled in the chance to plow through the dozens of now-online newspapers from the Civil War period–papers that I have never seen before. I have learned a few things along the way–most notably that it’s not long before you strike a point of diminishing returns: the source material pours forth, but what it tells us that’s new narrows (the entire field of military history as it relates to the Civil War suffers so). I have found thousands of wartime letters in the last few months, and while some are highly quotable, it’s a rare day that I find something that really goes beyond the interesting to tell us something new or important. Still, I realize that sometimes the significant emerges from the assemblage of tiny pieces.
There have been some spirited debates about the limits of online research. We all know researchers and writers for whom the research world begins and ends at their keyboards. If something doesn’t exist online, then they’re not going to see it. Indeed, it’s easy to imagine that we have a whole generation of historical thinkers who will be conditioned to find their material online, and largely only online. What does that mean to our historical work? I have been pondering a way to gauge just how important online resources have become, and I offer this little tidbit. Definitive? No. But maybe a useful reminder.
I went through the footnotes in seven of the 25 chapters of my book Return to Bull Run, which I finished writing in 1992 on the eve of the digital age. I looked at every citation in every footnote to calculate what percentage of them could be had online today. Going in, I guessed about 25% of the citations I included in the book would be available online today (by that I mean available on a permanent website; I did not include ebooks in the calculation, unless they were available for free use at Google Books or other archival site). I was wrong. Continue reading
