I'll use the Pillar New Testament Commentary set as an example.
I had the set prior to March Madness, but two volumes are now in the set that weren't there when I first bought it, so I purchased the set again to take advantage of the dynamic pricing offered as part of the MM sale--in affect, really only purchasing the two volumes I was missing. However, my order history doesn't list the purchase of those two volumes--it lists it as a purchase of the entire commentary set (at a ridiculously low price).
Now, I was pretty sure the two volumes in the current set that I didn't have, were Luke and Second Corinthians,--but how or where is this documented? There's no purchase date metadata that can be viewed within Logos that I'm aware of, but I thought, maybe still not too much of a problem--I'll just check my order history for my original purchase of the set and hope it will have a link to the commentary set as it was then (i.e. minus the two volumes). Then I'll compare the set as it was then to the current set. But there was no record of such a previous purchase in my order history. So I thought, "Great! It must have been included as part of a library purchase." That meant I needed to track down which library purchase included the Pillar set.
Well, I did find the library purchase that included Pillar, and by examining the volumes listed when expanding the Pillar entry in the library, I was able to confirm that the two new volumes were indeed Luke and Second Corinthians. But I'm hoping there's a better way. Does anybody have some good news for me???
AFTERTHOUGHT
It seems to me that since the price showing in my MM purchase was the dynamic price for just the two new volumes, the order history should also be able to document and display which volumes were purchased as part of that MM order. And/or (preferably "and"), an option should be included within Logos for a purchase date column for each resource when viewing your library. I know having a purchase date column has been brought up before.
