Looking for a cite for a Sartre quote

Copyediting an essay here & the author inserts a quotation from Sartre:

& I need to look it up (& get the page number & check it for accuracy). I gather it’s from Being & Nothingness, a doorstop-sized book, so I thought that before I actually start flipping through it doggedly maybe there’d be someone here who knows what page of the book it’s on?

According to this fellow, the quote is in a book by D.D. Palmer on Kierkegaard.
