From David Gascoyne, “Elegiac Improvisations on the Death of Paul Eluard” quoted by James Fergusson for his catalogue of books from the library of David & Judy Gascoyne:
While every printed page is a swinging door
Through which one can pass in either of two directions
On one’s way towards oblivion.
