The Harvard and the Reprints – like the links I have on here or the actual paperback reprints – are all good to cite. The idea is that the source is accessible to the readers.
What I’m still curious about is if the Harvard editions are a difference that makes a difference. Would love to see someone post some significant paragraphs from a Havard edition so then we could compare it to the reprints and see if there was a difference between the two. I assume the point of those editions wasn’t just to be an expensive book but to offer some scholarly value. That is an assumption I’m making since I don’t own any of the Harvard editions of the primary texts. I only own the Harvard editions of the essay collections and the notes.
