James,
The publications include the AAVSO journal and our own BAAVSS journal. I can’t find a way of identifying who the observers are from the Krakow database but I can see observation details including observers, on the Czech website (O-C Gateway). I haven’t so far been able to find any observations on the List of Minima on the Krakow website which also appear on the O- C gateway of the Czech astro society but AAVSO observations published in their December Journal are already on there. In future I think I will do as Jeremy suggests below and go through Des.
