I was pasting from GA 24 -- from a PDF that circulates -- and noticed that ὄρεξις had been OCRed as δρεξις, not a Greek word. I shouldn't complain, the quality of the GA PDFs just keep getting better with each new batch. But when I googled δρεξις, I discovered that there are hundreds of pages with the error, including pages from Aristotle on Google Books... I wonder how long before dictionaries have an entry for δρεξις: desire, De anima 433 a 9. File under digital hazards.
