Is there an SBL citation style?

I'm the author of the original SBL LaTeX BibTeX styles. This is no longer supported.

But for those who find this thread in google, you might be interested in a completely new implementation covering SBLHS 2nd ed. done in BibLaTeX.

See https://github.com/dcpurton/biblatex-sbl for source and issue tracker.

It's also available in CTAN and in TeXLive and MiKTeX.

It's much more flexible and robust than the BibTeX implementation, and much easier to maintain.

Have a look at this page: http://wiki.marshwiggle.net/doku.php?id=sbllatex:main There are many examples including some classes and packages dedicated to this kind of style.

You can find the corresponding .bst file here: http://svn.marshwiggle.net/sbllatex/trunk/bst/sbl.bst

The SBL style described here is basically an author-year style; in the bibliography, however, the year is not displayed right after the author name(s), but at or near the end of the respective entry. In case you want to use biblatex, you should load the package like this:

\usepackage[citestyle=authoryear,bibstyle=authortitle]{biblatex}

For minor modifications that might be necessary to create a "true" SBL biblatex style, have a look at Guidelines for customizing biblatex styles. To remove the "In:" for @article entries, use Herbert's answer to Suppress "In:" biblatex.
