Hi Fresh Fields -
Looks like the optical character recognition has missed a letter there. This does happen quite a bit, due to typographic errors/bad fonts/ink spots/etc, ultimately because OCR is imperfect in allowing for these things. It's enough to provide a pretty serviceable search facility across the texts, but it does have errors. However, this leads me into Althea's question...
We have indeed been investigating a way to correct these errors for a while. We've tested a system, it works just fine, but we've had a lot of other work on our plates that has delayed this. I'm a bit embarrassed, because I was hoping we would have been able to deliver this by now - we get so many emails about it, and it is something we've been talking for a while.
It will happen. It will!
