I haven't done the 'middle-click every link' exercise to check, but I wonder if some of them might become more obvious if the name of the fictional work was listed as well as the name of the character. I couldn't tell you off the top of my head what the Nightfall archaeologists' names were (though I suppose, given the Nightfall culture's distinctive personal-name system, they'd probably at least be easily recognised in a list of that nature).
