Think legal research can be done exclusively online? Maybe not quite yet. According to the Columbus Dispatch, many Ohio local governments maintain records in paper and … gasp … even on microfilm. With a life expectancy of 500 years, microfilm excels at preserving material like meeting records and ordinances.
Think the internet does a better job of saving information? As the New York Times reports, almost half of all links included in Supreme Court opinions no longer work.
Unless we can eradicate problems like link rot (and maybe Google should tackle this problem along with conquering death), the dinosaurs of the information world, including microfilm, will persist.
