I have just discovered the acronym SABLE that yarn fiends use - it means "Stash Accumulated Beyond Life Expentancy". I am trying to come up with a similar acronym for books. :D (It seems like it ought to be able to spell TROUBLE - To Read something something Beyond Life Expectancy. Because at my current reading rate, I literally have fifty years' worth of books on my to-read pile. If I never acquire any more ever.)
