This online supplement for students in PDF format from the Society of Biblical Literature (SBL) site gives pertinent information and multiple sample entries for footnote and bibliography entries, as well as a sample paper formatted in SBL style.
Unlike APA and MLA Styles, SBL style often uses footnotes rather than in-text (or "author-date") citations within the text of a paper or article.
The following samples demonstrate SBL Style formatting. But remember that your professor is the ultimate authority on how you should cite papers/assignments for his or her class (regardless of what the style manual says!).
