My previous post probably didn't answer your questions very well.

Unfortunately there is very little organization possible with the Archive (Cloud). We wish it allowed more than just listing items by title or author or date. I find it is easier for me to keep books on my Kindle/phone which I might want to read in the near future. That is, I pre-determine which books in my Archive (Cloud) I will likely want to read in the next few weeks and load them unto my device. That way I don't have to fish through a large list in the Archive (Cloud) to find one that looks interesting.
