The entries
What a scale bar promises
On most projections it is only true along particular lines, which is rarely stated.
Legends that need reading twice
Order, breaks and units, and what a legend leaves the reader to infer.
Three norths
True, grid and magnetic, and the angles between them.
Lettering on a sheet
Placement rules that were settled long before screens.
