RICHFORD, Vermont — When Colette Aubin-Roy unlocked the Richford library Thursday morning, she did what she has apparently been doing for a few weeks now: she counted the notes on the community board before anything else.

This time, there was one more than the night before.

Pinned beneath the handwritten reply to Aubin-Roy's own earlier note — the one that read Suite à venir / More to come — was a third message, written in French. In the margin, the author identified themselves as coming from Derby Line, not Richford.

For the people who have been watching the board grow over the past several weeks, it was the kind of detail worth pausing over.

"It's the first conversation on that board that's moved between two communities without anyone organizing it," said Marielle Trottier-Blais, a library volunteer who was present when Aubin-Roy opened Thursday morning. "Nobody passed a note. Nobody set it up. Someone from Derby Line just — joined in."

The board, a corkboard near the library's front entrance, has accumulated a loose and growing collection of handwritten messages over recent weeks — questions, responses, recommendations, a few jokes — mostly in French and English, occasionally both within the same note. The McGill collective, a small community reading and discussion group that uses the library regularly, had been understood as the informal connective tissue behind most of the exchanges. The Derby Line note, Trottier-Blais pointed out, carries no such affiliation.

Derby Line sits about thirty kilometers east of Richford, straddling what was once the border between the United States and Canada and now marks the edge of RONA's Northeast Kingdom corridor. It is the kind of town people pass through more than they stay in, though it has its regulars. Whoever left the note Thursday has not identified themselves beyond the margin annotation.

Aubin-Roy was measured about what it means — or whether it means anything yet. "I counted the notes again before I unlocked the door," she said. "I don't know what comes next. I just wanted to make sure I was seeing it right."

She confirmed she has not reorganized the board or added anything herself. The three notes remain where they were left.

Franklin County and the Northeast Kingdom have seen a gradual increase in informal cross-community contact since the border corridor stabilized in the late 2030s — shared market days, cooperative school programs, agricultural coordination through the Vermont Farmers' Alliance. What the Richford library board represents beyond itself is harder to say. But it is there, and people are writing on it, and now someone from another town is writing back.

Trottier-Blais said she plans to leave the board as it is. "Let's see if there's a fourth note," she said.
