I'm researching the topic of "head-dresses" in the Hebrew Bible for an encyclopedia entry, and was having trouble keeping all the various types of turbans and crowns straight in my head. This is an image of an Accordance workspace with several views of the Dictionary of Classical Hebrew, the standard multi-volume Hebrew lexicon. Needless to say, this kind of comparison would be very difficult with print volumes. Also, it is easy to click open a biblical passage and then "amplify" to any number of commentaries, textual notes, and multiple translations.
I love living in the future.
