I'll grant that Wikipedia has certainly gotten better. (And continues to do so!)
But it still tends to have large blind spots where the source is (a) pre-digital or (b) of interest to a relatively small total number of people.
Try heading to your local library or a used book store (Goodwill works in the US), find a technical or history book older than ~1980, then attempt to find the content in Wikipedia. Especially in history, the hit rate isn't good.
