This edition is very well compiled, it's easy to read, the size is right, and it is an excellent tool for studying the New Testament in depth. There are 3 sections, each providing useful information. At the front and back of the book, respectively, is a Greek-to-English dictionary and an English-to-Greek dictionary. And in the middle is a list of all the Greek words found in the New Testament. What makes this concordance better than most is that most concordances will only list what passages the word is found in - this concordance actually has the verse (or at least part of the verse) written out in English, with the English rendition of the Greek word italicized, so that you can see the context and see how the word is used in each verse, without having to manually search each verse in the Bible. Supposedly (I could be mistaken), earlier editions did not have any kind of numbering system; this edition uses Strong's numbering, which can be especially helpful if you're using an interlinear Bible or other text that contains Strong's numbering. This allows you to look up a word by the number, rather than having to find the actual Greek word (which may be difficult for people who are not yet familiar with Greek).
This is a great book. It makes studying the Bible in its original languages so much easier when you can see at a glance all the different ways a specific Greek word was used. I also like to look at the first and last mention of a word or count the number of times a specific Greek word was used in a particular book or passage, and it is very easy to do with this resource. I also have and recommend the Wigram's Hebrew Concordance. These 2 books save lots of time flipping through Strong's to find all the passages in which a particular Greek or Hebrew word are used.
