“Without books the development of civilization would have been impossible. They are the engines of change, windows on the world, "Lighthouses" as the poet said "erected in the sea of time." They are companions, teachers, magicians, bankers of the treasures of the mind, Books are humanity in print.”

“Books are the carriers of civilization. Without books, history is silent, literature dumb, science crippled, thought and speculation at a standstill. Without books, the development of civilization would have been impossible. They are engines of change (as the poet said), windows on the world and lighthouses erected in the sea of time. They are companions, teachers, magicians, bankers of the treasures of the mind. Books are humanity in print.[Bulletin of the American Academy of Arts and Sciences, Vol. 34, No. 2 (Nov. 1980), pp. 16-32]”

“Books are ... companions, teachers, magicians, bankers of the treasures of mind. Books are humanity in print.”

“Books are lighthouses erected in the great sea of time.”

“Books are Lighthouses erected in the sea of time." Prospero in Shakespeare's The Tempest”

“The written word is all that stands between memory and oblivion. Without books as our anchors, we are cast adrift, neither teaching nor learning. They are windows on the past, mirrors on the present, and prisms reflected all possible futures. Books are lighthouses erected on the dark sea of time.”
