Question for coordinator about online MLs

I'm wondering if spelling mistakes found in the MLs that are in the pubs sections are in the original letter or not. I'm assuming that you've scanned these letters, which means the mistakes are in the originals. I'm citing paragraphs 20 and 69 of The Devil Hates Sex, both of which contain minor errors. Are all the letters there scanned, or have some been retyped, in which case the errors may not be from the original.
