This one's been on the piles for at least a year now, and upon cracking it open today, I discovered it's an entire book full of quotes about books: reading, collecting, borrowing, defacing and, in the last chapter, the horrifying prospect of running out of them.
I read most of the quotes in the first half, but skimmed the rest, looking for citations that included names or book titles I recognised. Rugg gets bonus points for a collection that is not a retread of all the popular internet memes; there were very few quotes here that I recognised, and sadly for my TBR, a few titles that the stacks will soon be forced to take in and provide shelter for.
