“The Public Library—the written wisdom of the world at the fingertips of anyone with a library card! The average American pays $20 a year in taxes to support public libraries and can save that much by borrowing instead of buying just one or two books. A book that is loaned ten times cuts not only cost but paper use per read by a factor of ten.” from Seven-Plus Wonders of Sustainability by Donella H. Meadows
