I'm not that time-rich person (sigh!), but I've noticed the duplication. And you know what? I don't care! It does kind of irk me when I buy the same book in paper more than once (and yes, I have), but I often buy a book in hardcover and electrons on purpose. Years of buying Baen Webscriptions have inured me to having multiple electronic copies of a book on my hard drive.

Most importantly, though, I'm finding all these stories well worth another read.
