COMPENDIUM Brief summary of a larger work or of a field of knowledge : abstract
The library is more extensive, but they don't have the same goals. I'd even argue that part of Wikipedia's quality is it's ability to remain small relative to the knowledge it summarises.
You won't find a 1920's copy of a newspaper in Wikipedia, but you will find articles about events from then that link to said newspaper.
Both are super important though, Wikipedia can't exist as it does now without archives (digitized or at the very least referentiable).
