Dodson has produced the ultimate GNT Reader's Edition, with several features not found in Zondervan's or UBS's. The basic format of all three books is the same, the Greek text with the rare words defined in footnotes right underneath the text, so you don't have to flip to a dictionary. But this book includes all words that occur 50 times or less, whereas Zondervan and UBS only include those that occur 30 times or less. Plus, Dodson includes the number of times each glossed word occurs in the GNT. This not only helps you decide which words to commit to memory, but also allow you to chart your progress. (If you don't know a word that occurs 2 times in the NT you are okay. If you keep forgetting words that occur 45 times, you know you have some work to do.) Zondervan contains no parsing info at all on verbs; UBS has some, but this book parses EVERY verb in the GNT, but, unlike, UBS, it separates the parsing info from the glosses. This makes sense, because many people don't need much help with parsing, but will need help with the vocab for a long time to come.
But what really makes this the best Reader's NT out there are the glosses. UBS generally just gives a one word gloss for the meaning of the word in that particularly passage. Zondervan is much better, listing all the meanings of the word found in the GNT, forcing the reader to decide which meaning applies. But the glosses in The Greek New Testament for Beginning Readers are even more complete. They are concise, but over and over again Dodson includes interesting information that will delight the reader. I read through the entire book of Hebrews in this book, and even though I know the GNT pretty well, I found all sorts of useful stuff. Some examples of the glosses from all three books:
KEFALIS in Heb 10:7: UBS "roll (of a scroll of book." Zondervan: "roll NIV the scroll." GNTBR "(1) lit: little head, then: the knob at the end of wooden core of roll of papyrus) then a role, volume, division of a book." Heb 2:16 DHPOU: UBS "adv it is clear." Zondervan: "of course, surely" GNTBR "(1) of course, indeed, qualifying and yet strengthening the assertion." Heb 6:6 METALAMBANW UBS: "receive" Zondervan "I receive my share, share in, receive" GNTBR: "(6) (a) with gen: I take a part (share) of, share in, partake of (b) with acc: I take after (later) or take instead." In each case, Dodson gives you just a little more info while still keeping it brief so you can get back to the reading. I do not necessarily endorse all the points Dodson makes (he says of EURISKW, for example "I find, learn, discover, especially after searching.") but to me all his insights were interesting and worthy of thought.
And I have not even mentioned another reason for buying this book, even if you already own a Zondervan or a UBS. This text is the Majority/Byzantine text compiled by Robinson and Pierpont. Even if you are convinced that the Byzantine text is secondary, fairness requires that you read the text yourself to make sure. You will find that the text differs from the Alexandrian text underlying NA-27 very slightly, and you will find hundreds of readings that are shorter and "more difficult" by the standard criteria. The Byzantine text is a little smoother and more polished grammatically, and in my opinion is better for beginners. A sound historical argument can be made in favor of either text, so it is good to have them both.
And even if your Greek is pretty good, I think you will benefit from a reader's edition, which will help you nail down the last few vocab words you need. If all you own is a standard UBS or NA, this is the perfect second Greek NT to buy, since it will fill two niches, a Greek NT you can read in an arm chair, and exposure to a different text tradition.
My only criticism is that the font on the text is a little small, smaller than either UBS or Zondervan, though the font itself is very nice, non-italicized, and even nicer than than the UBS font. The binding of the book is strong and it opens flat. I'd like to see future editions come with a ribbon marker.
One final point about this book. Robinson and Dodson have released this book into Public Domain. The UBS/NA text has been copyrighted and sites which use the text have been shut down. UBS/NA doe not allow people to make audio recordings of their text. The publishers of this book should be applauded for their commitment to making God's LOGOS as accessible as possible.
