I'd like to organize my books into different collections and have a "completed" collection for books to be entered into upon their completion.
The problem is that it seems iBooks will allow a book to exist in only one collection, meaning putting it into "completed" takes it out of the other collection.
It also doesn't seem to allow users to add duplicate books. All of my books are DRM-free .epubs -- I could potentially put PDF versions of them into "completed".
What's your advice on achieving this workflow with iBooks and iCloud syncing?
