@Atherton: That setting only affects the OPDS and /mobile views. Not the main web interface. I'll add an example to the help string. You use the lookup name, which is the name you get by hovering over the column header in the main calibre program. As discussed way back somewhere in this thread with BetterRed, the web UI will likely grow some version of a preference controlling the displayed fields at some point.
