Working off a mobile ed section list of readings.
1. Those without the lock symbol, i.e. those I own, work great.
2. This one I don't own and it works great

3. This one I don't own and it doesn't work so great

If I click on the logos.com link:
- I am led to a page showing three collections but still not telling me what the resource is
- If I choose the cheapest of the collections hoping that it has the fewest books so the "right book" stands out, I get a collection of 7 books on John so topic isn't much of a help
- If I've been around Logos for a while I will intuit that SGF MMC is likely the initial letters of the title or of the name the book is commonly known by ... so near the bottom of the list of contents of the bundle I find: Symbolism in the Fourth Gospel: Meaning, Mystery, Community, 2nd ed. by Craig R. Koester Wow! It's only taken how long to find the title of the book referred to which I do not own.
- I won't even waste time wondering if other books in the bundle are used in the NT221 course or if this volume is used multiple times ... but Logos lost a potential sales.
