1. We followed her **up** the stairs to a large meeting room. 2. Put those books **up** on the top shelf.

"up" in the first sentence is a preposition, but in the second sentence it is an adverb. In 1, if you omit "up", you have: We followed her the stairs. In 1 "the stairs " has no relation to anything else in the sentence; the sentence no longer makes sense. So "the stairs " must be the complement of "up"; and "up" is therefore a preposition.

In 2, if you omit "up", you have: Put those books on the top shelf. In 2, the sentence makes sense. So "up" must be an adverb, which modifies the verb "put".
