There is a typo/error in the text! What to do?
At the top-right of every text page at the Archive (lecture, article, book chapter, etc.), there is a link called "Corrections" and beside it, a link called "Help." By reading the "Help" documentation, you can find out how to correctly submit corrections.
Please note: we do not correct punctuation nor word usage. We want each reader to experience the original documents just as they were published.
