The only changes made in the Book of Mormon are: It was broken down into verses for easier reference, and punctuation and spelling changes.
At the time it was written there was not universal agreement on how words should be spelled, nor how some punctuation was to be used.
In about the 1980s the church arranged for a University in England to put the Bible, the Book of Mormon, and the Pearl of Great Price through a computer process to make cross references. It was not done by BYU because they didn't have software capable of doing it.
You can now buy volumes that have the cross references printed on the bottom of the page where it applies.
There is also a Topical Guide where the cross references are sorted by subject matter.
They do not contradicts each other. You can buy the books and look for yourself.
You really don't know your own church history.........
OOps!

Dang!
That's just too bad!!
I guess NOW they could probably do it!
