I must say thanks for your rapid response.

That pdfs were not permitted, as it were, was the problem. On the other hand, the set-up is confusing to me, because I did get the conversion request, but I kept on saying 'no' to it, because I knew that I wanted, and could read, pdfs on my device--so that could use some tweaking. Personally, I'd rather have the error pop up on my Android thing, because then I know what is going on ("No reader available"), as opposed to the messages I got, which led me nowhere, despite my prodding around on both ends.

As for the news building up, Calibre definitely has the option of deleting things after x days. ("Schedule news download", at the bottom of that option dialog box, when you click the menu under "Fetch news".) It seems beneficial for this process to be automated, given its transient nature.

As for wanting more than one month's reading, a possible rationale would be reference books, such as cookbooks, or repair guides. I know, "The internet does this," but these things still serve a purpose.

Speaking of conversion... I mistakenly sent a converted file over to my device, and then the (original) format I wanted, and now I have two otherwise identical objects in the CC list with no ready way to differentiate the two. I would like to request some way to tell these files apart within CC, at least until I can delete them--but which one is the original, and which is the evil twin?
