How is this possible?

Someone has tagged books "yet untagged".

tag, you're it.

This has been used more: http://www.librarything.com/tag/untagged

Existentialism is wonderful - totally untagged.

Tag along

Perhaps they are waiting till they have read them before choosing a tag? And as an aside when I enter new additions to my library I generally add tags but often think it would be nice if I could see what others have used for the same book, perhaps others who have read the book and not just the blurb and a quick flick through.
Or is this a pseudo-philosophical issue as to whether books tagged "not yet tagged" are actually tagged?

But they have chosen a tag! They have tagged the book as "untagged", which is a logical impossibility.

I mean, technically, but it's only tagged to say that it's not been done yet. I can understand it, except that there's already the "(no tag)" non-tag (on the tag page, serving as a tag, without really being one), so doing it oneself is not necessary, lol. But if someone hasn't noticed that's there...
