I just saw someone on here express doubt about the value of teaching grammar, so I’m going to log off for the day and enjoy the forest 😊

"I must tell you that a horoscope which has been cast for my younger son shows that he will be pope, but I'm very much afraid he's more likely to be the antichrist."

That's it.

That's the *entire* letter.
Reading letters from the Princess Liselotte of Palantine, the German sister-in-law of Louis XIV, and it's wild because she had this super informal writing style that almost sounds like modern texts

Like at one point she goes "wish to god my son didn't love holding chunks of bread like a peasant"

A little plug for my article on Devon book sales c. 1700, which has gone online open access. tl;dr book auctions weren't just a London/Oxbridge thing: a flourishing second-hand book market centred on Exeter included auctions from the 1680s.

I’m in the Pacific Northwest for the first time in 5 years, and I had forgotten what it’s like to be deep in the big dark misty pine forest at night. A darkness I don’t often experience. Happy Thanksgiving!

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.

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.

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)
