Many people, other than the authors, contribute to the making of a book, from the first person who had the bright idea of alphabetic writing through the inventor of movable type to the lumberjacks who felled the trees that were pulped for its printing. It is not customary to acknowledge the trees themselves, though their commitment is total. ~Forsyth and Rada, Machine Learning
I thought this was a really quirky quote that made me think of the interconnectedness of all things. So next time you read a book spare a thought for the trees.
