Their stated goal:
Quote:Oxford Biblical Studies Online provides a comprehensive resource for the study of the Bible and biblical history. The integration of authoritative scholarly texts and reference works with tools that provide ease of research into the background, context, and issues related to the Bible make Oxford Biblical Studies Online a valuable resource not only for college students, scholars, and clergy, but also anyone in need of an authoritative, ecumenical, and up-to-date resource.
Easy to search and navigate, this site offers a ready access point for a wealth of Bible text and commentary—including the New Oxford Annotated Bible and five other popular Oxford Study Bibles—under the direction of a team of esteemed scholars headed by Editor in Chief Michael D. Coogan.
Texts from selected Oxford Bibles can be viewed in side-by-side display with the user's choice of commentary and annotations from the Study Bibles, the stand-alone Oxford Bible Commentary, and A-Z concordances for the NRSV and NAB translations. The Bible content is supplemented by collections of major apocryphal Old and New Testament texts in translation.
My favourite section:
Bible verses with side-by-side scholarly analysis of the text.
