Three years of no books in the living room, now ended

In a last-ditch attempt to save at least some of my antique religious volumes from Disraeli (the cat, not the PM), who finds them tasty, I have acquired a rather old oak bookcase.  With glass doors.  Alas, it has gone in the living room, which has been free of books since I purchased this house.  No more! Once again, the books take up all available space...

(Of course, given that I've had this awkward blank wall space, it was inevitable that the books would invade at some point.)
