Cite SBLHS is designed to produce apparatus (that’s citation footnotes and bibliography) for publications conforming to the Society for Biblical Literature's SBL Handbook of Style: For Ancient Near Eastern, Biblical, and Early Christian Studies (aka SBLHS). It is currently in an early beta stage. It also includes integration with Ibidem, the bibliographic management tool of Nota Bene.
