I need to stop buying books

BOOKS!

This week I acquired:

Einhorn's Old French Grammar (for some reason I did not own this! But now I do!). I feel supremely lazy because I ordered it online... from a bookseller in Sydney.

Tolkien's Legend of Sigurd and Gudrun. WHY? I don't believe it's even a particularly good translation - certainly Christopher Tolkien is not equipped to edit translations of Norse texts. But it was in Berkelow, and so was I, and, well, now it's on my bookshelf.
The collected poems of Banjo Patterson, and the complete short stories of Henry Lawson. Because I have this compulsion to acquire books which I appreciated from my father's bookshelf... Not sure why I do this, since I can't possibly take all my books with me when I move.
Foucualt's History of Sexuality.

Duby's Le Chevalier, la femme et le pretre and the first volume of Dames du XII siecle. My excuse is that Fisher doesn't own them in French, and I kind of need a copy I can scrawl on when I'm reading french. That's justifiable, right?

Sean O'Grada's Are you Irish or Normal. No excuse at all for this one.
