Famous quotes containing the word books:
“Ah, distinctly I remember it was in the bleak December,
And each separate dying ember wrought its ghost upon the floor.
Eagerly I wished the morrow;Mvainly I had sought to borrow
From my books surcease of sorrow—sorrow for the lost Lenore—”
—Edgar Allan Poe (1809–1849)
“PLAYING SHOULD BE FUN! In our great eagerness to teach our children we studiously look for “educational” toys, games with built-in lessons, books with a “message.” Often these “tools” are less interesting and stimulating than the child’s natural curiosity and playfulness. Play is by its very nature educational. And it should be pleasurable. When the fun goes out of play, most often so does the learning.”
—Joanne E. Oppenheim (20th century)
“Even bad books are books and therefore sacred.”
—Günther Grass (b.1927)
