To compare how much there is: plus de livres que toi, autant d'amis que moi. The de goes before the noun and the que before the second term. With a figure, de alone: plus de vingt. And to compare what something is like, there is no de.
The usual slip. Writing «plus que livres». Before the noun comes de; the que only appears before the second term.
Why it catches you out. English says more books than you with nothing at all between more and the noun, so you will simply drop the de. In French it is never optional.
