One of the owners told me that they get really excited when people from out of town order one of their signed books. It makes them feel loved. Don't you want to love one of our great independent bookstores?

In man or fish, wriggling is a sign of inferiority.

Narcissist versus reflecting pool = every humanities student nods approvingly, “makes perfect sense.”

In 2021 the current leadership of the Democratic Party had an opportunity to take radical steps to protect this country from trumpism. They failed. There are lots of reasons they failed, and maybe they would have failed regardless of whether they did this thing or that thing. But they failed.

Yes, histories at 250 are different, and largely because of research that broadened the aperture for academic and public history alike. That's good news in a year that can use some! Jane Kamensky wraps up by describing the energy in fresh approaches at Monticello. 🎁 www.nytimes.com/2026/06/22/m...

A dad joke in time for Father’s Day!

“College tuition will cost no more than 10% of parental adjusted gross income. That’s it. Grab the figure from Line 11a of your 1040 form, and divide by 10. Starting today, those are the instructions for anyone interested in applying to Whitman College, a small liberal arts college in Walla Walla”
