Famous quotes containing the words reference and/or clock:

    I think, for the rest of my life, I shall refrain from looking up things. It is the most ravenous time-snatcher I know. You pull one book from the shelf, which carries a hint or a reference that sends you posthaste to another book, and that to successive others. It is incredible, the number of books you hopefully open and disappointedly close, only to take down another with the same result.
    Carolyn Wells (1862–1942)

    He makes his voyage too late, perhaps, by a true water clock who delays too long.
    Henry David Thoreau (1817–1862)
