I use library books but have none currently, so am going from memory. I don't believe the date is indicated on the Kobo. I think that it is locked after it expires so you can't open it.
I use ADE to remove the library book after it expires from both the ADE library and from the Kobo. Note that the epub remained on my hard drive and I had to manually delete that.
If I have finished it before the due date, I use the little TINY dropdown to "return to library" (may not be exact menu item name.)
