Online Bible is another pretty useful sotfware program, but after a few revisions, you may have to buy the latest one to get some of the features that used to be free.
As for commentaries, dictionaries, etc, there are gobs of free classic works from conservative authors on archive.org.
I use on line sources to complement my hands on BiBle. There's just something about having His word ‘in my hands’ I can't explain...I get far more depth somehow then when reading it on line....more personal I think.
