Don't repeatedly concatenate onto the end of a string. Build up its individual parts in a table and use table.concat (). * by the reciprocal is ...
To access such an argument, use the "square bracket" form of table lookup: args ["author-first"]. Named arguments are indexed in the args table by their name strings, of course. Positional arguments (whether as the result of an explicit 1= or otherwise) are indexed in the args tables by number, not by string.
