Nah, from 2002 onwards people doesn't really have faith in
Encarta anymore. For example, I did a search in Encarta psd, return
a lame result: Social Democratic Party, Portugal
So never mind, I search again in full using power spectral density,
it show me articles on power instead.
Wikipedia is editable because the latest technology, math formula,
etc is updated constantly. It will never depreciate like Encarta
does.
What if you at you wits end? Online sources are limited, Encarta
all those doesn't have enough information? Only wikipedia have,
even it is baseless and wrote by some unknown guy. But it is
definately worth a try right?
