Great! That must have happened this week. I guess they heard the complaints!For what it's worth: Not sure when it went into effect, but the sources page now has a visible "In Library" tag on everything you own. Or most, at least - the Rrakkma adventure doesn't seem to have it, even though I own it, but I'm not sure that's purchasable on Beyond anymore for whatever reason, so it might just be an oversight...
Doesn't seem to apply to the marketplace (not yet, at least), but you should be easily able to see whether you own a particular book now.
