Greek Grammar on PrePublication

David Alan Black’s Learn to Read New Testament Greek is now on prepublication at Logos:

Learn to Read New Testament Greek is a user-friendly introduction to the Greek New Testament which offers insight into the language and thought of the New Testament writers. In this volume, David Alan Black provides tools and exercises for bringing readers to the experience of reading from the Greek New Testament after just seventeen lessons.

But I am at a complete loss as to why Logos is producing the second edition from 1993 when the third edition just came out in March, 2009 and has an extra 40 pages of content.

Strange.
