If I want to produce a referece like this in my bibliography:
Boncompagni, Baldassarre. Tre scritti inediti di Leonardo Pisano. — Firenze : Tipografia Galileiana, 1854. — 122 p. (in Lat.)
Do I use "Latin" or "langlatin" as my language? Because in biblatex manual it says it's either a literal or a key.
Where does it say that I need to add "lang" prefix to the language? And why do i need it there?
In the manual it says:
If localization keys are used, the preﬁx lang is omissible.
What are the localization keys?
This is very confusing - please help!
