The Society of Biblical Literature (SBL) has its own citation style for writing in the fields of ancient Near Eastern, Biblical, and Early Christian Studies. Use this style when your professor has instructed you to do so.
There is an online Student Supplement for The SBL Handbook of Style.
For the print manual in the library, see below.
