New tool by Harvard Law lets people explore language usage in caselaw

Thanks to my colleague Prof. Rebecca Lowry for passing on this article from the ABA Journal (“New tool by Harvard Law lets people explore language usage in caselaw” by Jason Tashea) about “Historical Trends,” a free online tool created by the Harvard Law School Library Innovation Lab which allows the public to explore the use of language over 360 years of caselaw in a corpus (linguistic database) consisting of 6.7 million federal and state cases and 12 billion words!

In what ways is it useful for LLM students (or any law students)? I’m not sure yet. If you figure one out, please let me know by posting in the comments or e-mailing me. But it’s fun to type in terms like “internet” and “res ipsa” and “synergy” and “irregardless” and “Lefkowitz” and then see the resulting graph covering 360 years of that word or phrase’s usage in American caselaw.
