I use the Skeptic?s site the most: http://www.skepticsannotatedbible.com/ There are links to other bible sites from there, http://www.skepticsannotatedbible.com/versions.html like the Jewish bible http://www.breslov.com/bible/bible.htm but that site is down a lot of times, so I utilize http://www.hareidi.org/bible/bible.htm . I use Bible Gateway http://bible.gospelcom.net/bible?language=english frequently because you can search by words or by text in multiple choices. It also has translations into about 20 languages. I use English and Spanish bibles. The English one has the following bibles:
New International Version
New American Standard Bible
The Message
Amplified Bible
New Living Translation
King James Version
New Life Version
English Standard Version
Contemporary English Version
New King James Version
21st Century King James Version
American Standard Version
Worldwide English (New Testament)
Young's Literal Translation
Darby Translation
Wycliffe New Testament
New International Version ? UK
I employ the Septuagint http://www.ccel.org/b/brenton/lxx/htm/TOC.htm once in a while to compare texts.
Early Christian Writings http://www.earlychristianwritings.com/ has many books that could?ve been included in the bible but were not.
