Here's a little plug for eSword. I haven't used it but two times now, but so far, I think it's really handy to have the software on my hard drive for instant referencing.
The default download comes with the King James Version (authorized and with current spellings to a degree — I didn't check the copyright date) and Strong's numbers and Strong's dictionary.
Then, you may download many also-free modules that install very easily. There are other modules available for a charge. The worker does deserve his wage.
Since I'm not mister megabucks by any stretch, I'm only using the free versions so far.
This post is my way of sending some traffic to the software author and to help spread the word that is love.
