Why does everyone call the Greek-English Lexicon of the New Testament and Other Early Christian Literature BDAG (Bauer, Danker, Arndt & Gingrich) but its abbreviated title in Logos is BAGD (Bauer, Arndt, Gingrich & Danker)? I know I can change the abbreviation to whatever I want, but I'm just wondering if this is metadata that should be fixed, or are there two legitimately used shortcuts for this resource? Which one is "preferred"? (Acronymfinder.com lists both.) I seem to recall something about the acronym for this changing when a new edition came out. The edition listed on Amazon.com is called BDAG (on the front cover); it's the 3rd edition. It's not clear whether this is the edition included in my Logos library. The cover image in my library looks like the older edition (I wish I could zoom to see a larger version of the icon to make out the text on it; I'll submit that as a suggestion). Was the older edition called BAGD? Do I not have the latest version that Logos ships? (The current Logos edition listed on their website is very clearly the 3rd edition with the newer cover art.) Is it free for me to upgrade to the newer version? If so, why hasn't this happened automatically when I sync resources? This is what I've got now:

Incidentally, the authors are listed in my Logos library in the order: Arndt, Gingrich, Danker, and Bauer, which isn't either BAGD or BDAG, and it isn't even alphabetical, so where did that come from?
