Wow! What I wouldn't have given to have had this when I was a student. (Actually, what wouldn't I have given to have a computer as a student). I well remember the two volume Bosworth and Toller -- a hard slog to lift off the shelves, even harder to use, but the only authoritative source for OId English.

Needless to say, I flicked backwards and forwards in my Klaeber Beowulf for the vocabulary, rather than using Bosworth and Toller.

But this! As an application it's fairly middle of the road. As a release of powerful information to those who want or need it, it's immense. You type in part of the word, it finds everything which fits. No worries about eth, thorn, yog and wyn. If you just type in 'th' it finds the eths and thorns without any worries.

Everything is very cleanly laid out -- another huge improvement over Bosworth and Toller's printed edition -- and the application runs very fast.

Of course, if you aren't translating Old English, this is completely useless -- but, if you aren't, why are you reading this review at all?
