Choosing a gift for the four-year-old niece I am meeting for the first time tomorrow, I was overwhelmed by the picture book options and how so many seem to have thinly disguised lame morals like “learn to share” and “regulate your toddler emotions”

Today's theme is - not actually cards, but weird enough to merit sharing. First up - the cover of Farmer's Wife. What did he do? Is he still thankful? Is she thankful that she doesn't have to put up with him at Thanksgiving dinner? So many questions. #thanksgiving #farmlife #stocks

How many books is unreasonable to take on a cross-country Thanksgiving trip? 4? Unfortunately I’m 2/3 through a 700p. book which I’m going to carry and probably finish on the plane…

On a more cheerful note, I’ve been frantically banging out an illustrated list with a spooky occult theme just in time for Christmas 😅 look out early next month!

Restraining myself from posting on ex-libris about ViaLibri’s “AI research tool” that their “ceo” claims to be building with listing data. Not worth the fight this Thanksgiving Eve, and I suspect people’s responses would disappoint me.

Nice case of a fake '1584 Viterbo' edition, undoubtedly printed in Paris in the 1620s.

Our books are inherently non-commercial, art objects. I talk about this a lot in bookshop circles but, people don't hesitate to support dance, visual art, and other modes of artistic expression that are totally nonprofit but culturally valued. Why do people not apply that to books and literature?

Also, the idea that the proposed exercise is necessary to teach students that LLMs aren’t “primary sources” is baffling to me. There seems to be something very wrong with the teaching about what a primary source is if that’s the case.
These assignments encourage people to become DIY detectives, exacerbating a boom in conspiracy theories. The “permission structure of doubt” normalises suspicion as a default setting and suggests that another algorithm (like Google’s search) can discover the truth.

How is it that college administrators get paid high salaries to come up with such dumb ideas, over & over again...? Is there someone who will pay me for dumb ideas? If you really want I can come up with plenty (and even some good ones as well) www.nytimes.com/2025/11/19/n...

I wish more reporting on this made the point that novelists won't be displaced by LLMs suddenly producing literature instead of story mulch, but because decision makers focused only on the bottom line, who don't understand what makes a good book, will be persuaded story mulch has got 'good enough'.
New research by @mctd.bsky.social shows the impact of generative AI on authors in the UK. They found over a third of novelists report their income has already been negatively impacted by AI and 85% expect their future income will be negatively impacted.

Fun fact: in the Bibliotheca Casanatense, book theft didn’t just get you in trouble—it got you excommunicated on the spot. (At least that’s the warning that was hung up at the library)

One of my problems is that I don’t really want to do scholarship, I just want to write in a historically informed way about my feelings about Plato. And I’m not sure there is really an audience or venue for this.

saturation with Tolkien spinoffs has somehow not prepared our culture for the arrival of dark lords bearing a gift that everyone becomes convinced they can wield to accomplish great things but just makes them dependent and start whispering about preciouses if you suggest just throwing it away

As a child I watched some TV show (unsolved mysteries?) about Spontaneous Human Combustion and was extremely concerned about it for many years after
Good to see the kids’ section of our local bookstore still carries the classics.

Working with the chief curator on the catalog for The Edible Monument, our editor queried a line about a festival “celebrating the King’s return to health” & I was put on the case. Turns out it was the anal fistula surgery recovery festival—a detail which did NOT make it into the final text.
We begin today with a content warning: this dispatch from history is not for the faint-hearted. However, if you wish, do please join me for the tale of the Sun King’s anal fistula and the three-hour operation performed on it without anaesthetic on this day in 1686... 🧵

test the plausibility of this for yourself: ask "what sort of efforts would fully counteract the sociological effects of a system where people routinely sold their own children into labor camps?" and see how different your answer is from "years of open terrorism in defense of retrenching apartheid"
The south was a chattel slave empire until the 1860s and a de facto ethnic authoritarian state for the following century, which is well in living memory. I don't think we need to pretend that that hasn't left a distinctive cultural mark.
