Considering articles, I suggest the following additions:
Une (french)
L' (french)
Les (french)
Il (italian)
Gli (italian)
Lo (italian/spanish)
Los (spanish)
Las (spanish)
De (dutch)
Het (dutch)
Een (dutch)
I think it is a good thing to ignore articles in subject ordered lists.
Traditional german library instructions do exactly this.
