I ran across a couple claims that relatively only a few words make up most of the written material in English -- namely, that the most popular 100 words account from a third to a half of all content written in English -- and although it looks plausible enough on the surface, I wanted sources. However, I couldn't find a reputable source anywhere, just the same tidbits repeated all over the place.
The most trustworthy secondary source I could find was this blog post from dictionary.com, but I'd say trustworthy only because you'd assume they'd have some incentive to take associating themselves with this claim seriously.
It seems the problem stems from the relevant research available being from before the internet, or even personal computers, and so it wasn't digitized, only passed down like oral tradition. Apparently there's no recent research on the topic, at least none that I could find.
Can anyone point me to anything more substantial on the topic? Thanks.
