Crossway have created ESV online, a free online Bible study website. If you register, you can create your own notes, highlight passages, place bookmarks, and customise your own view. All of this for free.
Note: they've provided a 30-day trial access to the ESV study bible notes & resources. But after the trial, you have to pay for it. Cunning... :D
Incidentally - I have no personal or financial interest in Crossway - I'm just glad to see useful bible study resources made available.
