I've used a number of different Bible Software over the years such as
e-Sword,
Pradis,
Libronix,
the SWORD Project and
Bible Explorer.
Libronix is easily the best one, unfortunately it is also very pricey. Pradis is difficult to use not to mention just as pricey as Libronix, and often when a new upgrade comes out, your old books will not transfer, which means you'd have to buy them all over again. I'd stay away from Pradis. Both e-Sword and the SWORD Project are relatively easy to use and have a wide-range of free books. I have to say that Bible Explorer is probably the best one out there for the common person. Libronix is better, of course, but the books are much more expensive. If all you are going to do is read, the Bible Explorer is the one for you. For serious study, then Libronix.
I have been amazed at the excellent prices for books for Bible Explorer.
Doxa Digital Press has provided a number of excellent books at very cheap prices. They have all 52 volumes of A. W. Tozer for
$35, or about 60¢ a volume whereas Libronix has it for
$190 on sale ($3.33 a volume), with their normal price being $399 ($7 a volume). For me, it would make obvious sense to get the $35 version than the $190 version, as these are just simple books that I am going to read. If it was something complex like a Greek NT, then Libronix would have much more added value to it.
I also purchased a collection of 5 of Louis Berkhof's Theological works for
$5.95. That's hard to beat.
Rejoice Software carries a lot of the titles (the guy who operates the site is the guy behind Doxa Digital Press). If you subscribe to his e-mail list, you'll get an e-mail about once a month with a special.
So go check it out. Download
Bible Explorer 4 and then look for the free books in the
catalog. There are 181 of them right now! Go
here and you can download all of them, plus the ESV.
