This has nothing to do with the library of Ashurbanipal itself, but is still worth mentioning. Ashurbanipal's library gets referenced in the VERY clever parody song "I Am the Very Model of a Biblical Philologist", which you can watch on the author's channel here: https://www.youtube.com/watch?v=3x2SvqhfevE (video is under 4 minutes long).

Depending on your knowledge of ancient history and archaeology, you may find the song either mildly funny, or side-splittingly hilarious. (And no particular religious position is advanced in the song, it's pure silliness. Putting that out there in case anyone was worried by the title). Personally, I landed on the "hilarious" side of things, which is why I wanted to share this video with you all.

I hope this brightens up your day a little.
