I think archiving the world's books is as valuable as websites. Many books represent years of an author's life writing authoritatively on a subject. And there are a staggering number of books (especially before 1980) that are simply disappearing from the public record. As book production goes digital and titles are increasingly sold as digital "leases" that customers and libraries don't own (i.e. kindle, libby, etc), it's becoming more and not less challenging (counter-intuitively) for libraries to archive and preserve books into the future. And that's not a coincidence. And I wouldn't be surprised if we continue to see a steep uptick of similar challenges for archiving the web.
