The Vanished Collection Reappears on Fold3

I recently wrote about a collection of Arizona World War II Draft Registration cards that appeared in the FamilySearch.org Historical Record Collections and then disappeared without any notice. Well, apparently, there was some negotiation going on because the collection showed up on Fold3.com as a "newly" added collection. No problem for me, I have access to both programs.

But perhaps this is a word to the wise that collections may end up moving from a "free" program to a subscription program without notice. I suppose this is good reason for making digital copies of the documents to your own computer database rather than relying entirely on online sources for storage. Don't get me wrong, I think moving as much as possible to online programs is a good idea but now I will try to be more careful to also keep a copy of all that I find on my own computer.
