For the purposes of study and teaching, I will be using the 2013 Edition of the Scriptures produced by The Church of Jesus Christ of Latter-day Saints.
Further information on this edition can be found here.
In addition, some wonderful articles regarding textual changes to scriptures can be found here:
Understanding Textual Changes in the Book of Mormon
The Value of New Textual Sources to the King James Bible
