The list author says: "I love the Counterpoints series by Zondervan, but am having trouble finding a definitive list of the books that have been published in the series (even Zondervan's own website is missing some of the titles in the series). This is my own attempt to finally create a definitive list. If you know of any more that I've left out, please drop me a line and I'll make sure and get them in here.
It appears Amazon doesn't carry every one of the books in the series, and some are out of print. Wherever possible I've linked to the copy sold by Amazon, but in some cases I've had to included copies being sold by third-parties."
