Actually, by spelling things out, we aim to make people feel more comfortable ordering books: it's clear that we've thought things out, and that there isn't some "mistake" you're going to make ordering (say) a copy of K&R2 when there are already 2 copies in the office ("your book privileges are suspended, Peter!").
