Should a dagger (obelisk) come before or after its reference word?
This symbol looks like a cross, sometimes refered to as a printer's mark
(†) used esp. for references.
Definitely after, just like a regular asterisk when placed in the main body of text. Then, before the referenced text when used in the footnote.
It is actually just another different looking asterisk, for when you need to highlight multiple references, so the same logic applies.
Required, but never shown
