Hello. I have been transcribing typewritten letters. For some of them, the author went back and handwrote corrections to what she typed. For example, she had typed "i n", and then made a pencil mark showing that she had meant "in". How should I transcribe that?
I suggest transcribing this word simply as in, with no additional comments or information added to describe the edit. If this edit was more consequential and had more meaning rather than correcting a typo, then you might want to indicate this with a note to that point in brackets ex. - [handwritten insertion of the word XX].
