Kaelbling, Littman & Cassandra's own pre-publication documents — their 1994 AAAI conference paper and their 12 February 1998 preprint — correctly date Åström's paper to 1965

Every document the three authors themselves produced and controlled before the final 1998 journal typesetting cites Karl Åström's paper correctly. Kaelbling, Littman & Cassandra's own pre-publication preprint — self-hosted on Cassandra's site, footer dated "Preprint submitted to Elsevier Preprint," 12 February 1998, roughly the same production window as the final journal issue — reads: "K. J. Astrém. Optimal control of Markov decision processes with incomplete state estimation. Journal of Mathematical Analysis and Applications, 10:174— 205, 1965." Four years earlier, the same three authors' AAAI-94 conference paper, "Acting Optimally in Partially Observable Stochastic Domains," both cites the source correctly inline ("The belief M pp is Markov (Astrom 1965)") and lists it correctly in its own reference list: "Astrom, K. J. 1965. Optimal control of markov de- cision processes with incomplete state estimation. J. Math. Anal. Appl. 10:174-205."

Combined with the misdated final version, this establishes a clean before/after boundary: in every document the authors wrote and controlled directly, the date is right; only the final, typeset, published edition — and copies descended from it — carries the wrong year.
