The NRSV may be a little more difficult for people with lower reading skills, but it is closer to the original language text. The concordance and maps are helpful, but this is not a full study Bible, this is a light-weight Bible that is compact and easy to read.
We love the HarperCollins NRSV Go-Anywhere! It is a great gift that we hope our students will treasure for years to come! And no worries that they all have the same one-- Christianbook.com does a great job imprinting their names on the covers!
My new church uses NRSV and my Bibles were NIV and NKJV. I wanted the version being used in church so the words would be the same. I also wanted a Bible small enough to fit in my hands, light enough to carry in my work bag, and with print large enough to read. This Bible meets all of those requirements.
