Why isn the Old Testament included?
It’s a practical issue in two dimensions. First, it takes a lot more processing/storage/management. But even more importantly, the size of the link pages becomes much less tractable for all but the most infrequent words. You could mitigate this with a more powerful interface that controlled the quantity of results that were shown: that goes beyond my limited skills and ambitions, however. Primarily, i see the Hyper-Concordance as an experiment in alternative navigation methods. It certainly does not reflect any disinterest on my part on the Old Testament, its content, or overall message.
