I have a reference to an Inquisition Post Mortem that should be archived as C 142/83/20, but it doesn't show up in the catalogue. And all the Help Desk can do is tell me that. I've searched by every set of keywords I can think of but nothing comes up, so I don't think it is there under another reference. The catalogue shows C 142/83/3 as the first of that collection and the next in sequence is C 142/83/150; I'm hoping that it is there but just not yet registered. But the only way to know is for someone to physically check.
