I have a sizable library, and I would like to push to my librarything account only the latest aditions. That has a lot of advantages: more laptop battery for me, less consumed bandwidth, minimal waste of resources on the librarything servers. Only drawback is that I don't know how to do a search for books added only after, say one month ago. I could employ a certain tag that would be attached to all the exported entries, but that means some overhead and each tag translates into slower processing.
