Prompt: The oldest book in your TBR pile/list

[Stina]

Interpret this however you like. I'm taking "oldest" to mean has been on my TBR for the longest time. I was pretty much born with a TBR, so this means any of the books I've been meaning to read since I saw them on the shelves of the family library when I was a child. Aku-Aku: The Secret of Easter Island, which I started last year for the armchair travel prompt but never finished, counts. So does On the Beach, which is much, much shorter.

"Oldest" could also mean the physically oldest volume in your stack, or the book that was originally published the earliest. And it's entirely up to you if your TBR for this purpose is physical or virtual.

In Search of Nature is the one on my Bookcrossing TBR the longest, but Born to Run has been on my Goodreads TBR longest. So one or the other will do.
