It does transcribe books (through imperfect OCR) so I guess that's possible. Never relied on it as I search by title and author.

But anyways not the case for the wayback product which is the unique core to IA.

That's not unique, not a product, and not the part I use most.

Well, OK, maybe other webpage archives don't work as well, I haven't tried them, but there are others. And they're newer, so don't have such extensive historical pages.

Large numbers of Wikipedia references (which relied on IA to prevent link rot) must be completely broken now.
