I see someone has been reading the register a bit too seriously. That article completely ignores the kind of errors counted and its treatment of error rates is completely false (I never knew "badger" was correct when discussing Isaac Newton).Oh you did not just refer to Wiki as a good source of information, did you? It has good bredth, it has some good articles, but it also has 30% more errors than the Encyclopedia Britanica. Also, wikipedia will inevitably go with common knowledge, which isn't always correct.
Not only that, but a hard-copy of Britanica runs at about $570 (469 euros) and the electronic version is a piece of garbage.
Also, Britanica goes out of date as soon as you get it, which is just as bad as having errors.
