About a month ago, I posted on Bible software and a good follow-up to that post is this review of 6 different free programs, including Swordsearcher, e-Sword, BiblePro, Theophilos, The Sword Project, and the Online Bible. The reviewer concludes thus:
Narrowing the field down to Swordsearcher and e-Sword was easy; picking the final winner was not. I went back and forth trying to come up with a clear winner, but in the end I gave up. My conclusion is that both of them do about 90% of what I need, and therefore I was going to have to go against my anal-retentive inclinations and leave both products installed on my box.
I have come down on the side of Swordsearcher for general day-to-day use, using it to do my research and enter my own commentaries and works. However I switch to e-Sword when I need to find text in a contemporary translation, or need to see a parallel view of a passage from different translations.
But read it all to see the pros and cons of the various programs and which would best suit your needs.
