Hi
I spent some time this afternoon to look at each of the resources in the Portfolio Package, to be a good steward I do the usual compare price resource by resource. I found this typo

Near East Archaeology Collection (4 Vols), shouldn't it be (3 Vols) instead? according to

It also can be found in the Upgrade Offers ....
After taking into consideration of the many resources that I have already owned, just counting those that I have not owned ... mathematically, the $number$ speaks for itself ... I was tempted, I yielded to temptation and have ordered the Portfolio Upgrade.
