How do I edit my literary works?

I can't figure this part out. I want to act on the reviews, but without knowing how to edit my works, I have to either post a comment with a revised edition or sit there helplessly. Where do you find the button or whatever that lets you edit?

Look to the right of the screen, under your avatar. There should be a "Tools" heading, with a button called "Edit Work".

Thank you, found it now!
