With some of the resources which are being added, the ability to do a fuzzy search is becoming a necessity. For example, if you look at The Book of Common Prayer according to the Use of King's Chapel you will find that they have very carefully noted all the Biblical sources for sentences and phrases. In contrast, The Book of Common Order (Knox) doesn't note them at all. To be able to identify the sources in Knox so that I can compare the use of scripture in the two services, I need a fuzzy search ... or a guarantee that I have all the relevant historical Bibles[:D]
