You wouldn't be allowed to make derivative works of those books; i.e. copy/paste into your own work.

Google isnt making new books, or enabling people to make derivative copies; it is merely previewing a book.

Github search is a preview. Copilot is a copy/paste.

What about Google Books Ngram Viewer? Isn't that a derivative work based on copyrighted content? It's more than just a search or preview - it contains both novel information and snippets of existing content. Is linguistic corpus a special case?

The research value actually turned activity that would be infringing into activity that was not infringing. Take away things like the ngram viewer and Google Books infringes.
