Dan,
The KJV is not copyright protected. It can't be. Neither can the earlier translations. The VERSIONS modifying content, making notes, adding notes, content, colors, study systems, etc can be trademarked and copyright protected. This is the only way people can make money on the bible.
If you have purchased the license for work on a CD, DVD, VHS, etc, it is legal for us to make copies of them for personal use, not for others.
Libraries do not violate copyright laws. Read up here:

Libraries DO buy books. They have dedicated sales channels to publishers. Sure, libraries can take donated books and materials. This is just the way it is.
When I was a kid, I had no idea about this stuff. I was an audiophile type though. So were my friends. We did not lend LPs to one another because we did not trust the other guys to use good turntables with the proper weight of tone arm, cartridge and anti-skate. I had pretty good tape machines and did not want tapes that had been played in car stereos and boom boxes in my decks. Tape shred and cassette chassis types could jack with my deck's transport and heads. All that is to say, I COULD have done it, but it was not likely. Again, it was not because I knew the law. Truth is, not many people paid attention AFAIR. So this is no pat on the back for sure.
There was one exception to the rule. My pal Dennis and I would go in half and half on new music releases. We would gamble half each. If we liked it, we would go back and buy a second copy and both have one. We did this with the first Stryper record, Yellow And Black Attack.
I would be willing to bet enterprise software theft is just THU-ROO THE ROOF, easily eclipsing the entertainment theft.
