Books in Books Lists on LibraryThing

Lists didn't yet exist when most of the chat happened here, but they are an excellent way to collect the real books mentioned in other books. These are some I know about:
https://www.librarything.com/list/349/all/Bibliography-for-Among-Others
https://www.librarything.com/list/43070/all/Books-mentioned-in-Fire-and-Hemlock-...
https://www.librarything.com/list/43805/all/Books-Mentioned-In-The-Chalet-School...
https://www.librarything.com/list/1177/Books-Featured-on-Gilmore-Girls

There's also this lovely list
https://www.librarything.com/list/43060/all/Books-that-contain-themselves

Anyone got some more?

And by some strange coincidence right after posting this I found a list on a backup drive that I made in around 2006 of the books and authors talked about in Pamela Dean's Tam Lin, so I added another list:
