Note: This question applies to the NIV, Amplified, NASB, NKJV, RSV, NRSV, NLT, and ESV.
All of the translations that are available on our Bible Search are uncopyrighted; in other words, they are in the Public Domain (at least in the U.S.), meaning that anyone may freely use, publish, or redistribute them.
Unfortunately, most modern translations, including the NIV, Amplified, NASB, NKJV, RSV, NRSV, NLT, and ESV, are copyrighted, which means that we are forbidden by law from redistributing them unless we obtain explicit, written permission from the publisher of the particular Bible version in question. That can be a cumbersome, time consuming, and potentially expensive process. Nonetheless, it is our long term goal to obtain permission to include as many of these translations as possible in our Bible Search.
Although at this time we are unable to make those versions available on our Bible Search, we are permitted to use them as part of our Daily Bible Verse and Weekly Wisdom explanations, because the publishers of all of the translations that we use grant permission for limited uses, such as short quotations.

Both are New Testament manuscripts. NU is short for Nestle-Aland and United Bible Society Critical Greek Text, and TR is an acronym for Textus Receptus, which is Latin for Received Text. The New Testament of the King James Version was translated from the Textus Receptus. For more information about the Textus Receptus, see What is the Textus Receptus?
