This document discusses and compares the Encyclopedia Britannica and Wikipedia as knowledge sources that are dependent on technology. It notes that while the EB was first published in 1771, Wikipedia launched in 2001 and has since grown rapidly due to its open wiki model that allows collaborative editing by people. A 2005 study found that Wikipedia entries contained on average 4 inaccuracies while EB entries contained 3, indicating their comparable accuracy. It questions how knowledge is defined and produced in the digital age.
