Then your publisher / store must have changed. (this is one of the issues that there is no 'correct' way. We can just hope they just spell it
correctly 
)
Just like:
title_series_sorting = 'library_order'
I grew up using that
card catalog located in the middle of the Library.
"A" and "The' did not appear first on the Title card.
Phone books were Ln, Fn (White pages)
The current generation wants it the way it is said (Stupid Siri
)
