Big Data makes the past more present. Recently, a website provided a virtual tour of a picture exhibition that Jane Austen saw in 1813. This site demonstrates how information technology, including big data, can make us closer to the past than ever before. Indeed, we are becoming in some sense closer to past than the denizens of the past themselves. Few people in 1813 attended this famous exhibition, but everyone today is only a click away from a virtual tour. This increasing capacity has large implications in subjects as diverse as literary criticism and constitutional interpretation.
For instance, another example of our capacity to get closer to the past would be our ability to map all the uses of a word (like commerce) at the time that word was used in a document (like the Constitution). Few people could attend the 1813 art exhibition but no one in 1789 could systematically catalog all the uses of a word.
