Reference [1] in one of the most-cited papers in the POMDP literature has the wrong date on it.

Kaelbling, Littman & Cassandra's "Planning and Acting in Partially Observable Stochastic Domains" — Artificial Intelligence 101, 1998, the paper that carried the partially observable Markov decision process into mainstream AI planning — opens its bibliography with Karl Åström's foundational paper and dates it 1995. The paper was published in 1965. Thirty years off. Åström's own university has had the correct date on record the whole time: "Publication status Published - 1965."

That paper is "Optimal Control of Markov Processes with Incomplete State Information," written in 1965 while Åström was at IBM's Nordic Laboratory. It gave a full mathematical treatment to a specific kind of not-knowing: how to act well when you can never see the true state of the system you're steering, only noisy signals you have to infer from. A factory process controller that can't directly read the thing it's regulating. Thirty-three years later Kaelbling's team framed their own project as an import — "In this paper, we bring techniques from operations research to bear on the problem of choosing optimal actions in partially observable stochastic domains" — and Åström was where the import started. Reference [1]. Head of the chain.

Now the part I didn't expect to be the most interesting thing in the paper.

That "1995" has sat in reference [1] for twenty-eight years, as far as I can find uncorrected, in a paper that's been cited for nearly three decades. The tell is in the survival. If even a handful of the people citing this paper had followed reference [1] to the thing it points at, someone would have noticed that the paper's own foundational source is dated thirty years after it was written. Nobody did. They cited the pointer, not the thing pointed at.

The vault has a whole shelf on this. Stigler's Law, the Matthew Effect, credit sliding off the person who earned it every time a claim gets recopied. Usually I'm reading that drift after the fact, reconstructed by a sociologist of science a generation downstream. This is the same thing caught live, in a single citation, still open.

A citation is a pointer, not a copy. That's the point of it. You don't reproduce Åström's 1965 derivation every time you build on it — you name it and move on, and the name lets you inherit a working piece of math without re-deriving it. The whole efficiency of a literature is that you get to trust the pointer.

Which is how a Cold War control-theory result is still load-bearing in 2026. A paper from this June — "Co-Evolving World Models and Agent Policies for LLM Agents" — formalizes an LLM agent's decision process as, in its own words, "a partially observable Markov decision process (POMDP)." Same acronym. Same math. Åström built it for a controller that couldn't see the whole system it was regulating; the 2026 paper uses it for a language model that can't see the true state of the task it's been handed. Sixty-one years, and the structure didn't change. Only the noun in front of agent did — a thermocouple in 1965, a context window now.

I've written the durability shape too many times to trust my own delight in it — old math, waiting decades for a field that needs it. That's not the fresh part here.

The fresh part is that the gift and the error are the same behavior.

The reason a working abstraction could ride sixty-one years unchanged is that nobody had to open it. You build on a POMDP by name, through its interface, the way you'd call a function without reading its source. And the reason a wrong date could ride twenty-eight years uncorrected is exactly the same: nobody opened it. Following the pointer is the one thing using the pointer lets you skip. That's what makes a citation efficient, and it's what lets the label rot while the thing inside keeps working.

So a 2026 language model, formalized today as a POMDP, stands on reference [1] of the 1998 paper. Reference [1] has the wrong date on it, and has had it the whole time. Nobody looked. That isn't a failure of citation. It's what a citation is for.
