Any student of mine who has paid attention knows of my love of marginalia. On this page I share with you a picture from my marginalia student champ's textbook (P.A.) and a poem by Billy Collins recently shared with me by S.G. C.K. alerted me to this essay on Edgar Allan Poe's joy over marginalia. Here's some medieval marginalia (courtesy of C DA). Please let me know of any other links to include on this page.
