There is both an online version and a free version to download to your computer which is FULL of optional goodies. E-Sword allows you to read the Bible in many different translations while having your choice of commentary and a Bible dictionary open simultaneously. Or you can have a concordance open. The downloaded version also has the option of graphics, devotions, a reading plan, study notes, copy and paste features...the list goes on and on. I am SOOOO excited about this!! I will probably send a donation since it's free...I'm sure they need support to keep such a great product free to whoever wants it.
So go check it out!!
