If you go to the project folder there should be a file called booknames.xml. This should give you what you are asking for. The format looks like this:
<book code="GEN" abbr="Gén." short="Génesis" long="Li Hu Génesis" />
<book code="EXO" abbr="Ex." short="Éxodo" long="Li Hu Éxodo" />
<book code="LEV" abbr="Lev." short="Levítico" long="Li Hu Levítico" />
As always - be very careful doing any editing in any xml file if you are not sure what you are dong.
