Adding outside reading?

I’ve started doing some outside reading of kids books and I was wondering if any of you had an efficient way of keeping track of that in LingQ?

I’ve decided I don’t want to go through the process of removing DRM from e-books. And I’ve actually re-typed one book to include it in LingQ, but that’s not a great use of my time.

Right now, the only thing I can think of is updating my “words read” stats and creating a list of unknown words from whatever I’m reading that I then type up and turn into a LingQ lesson. But neither of those update my Words Known number, which is my favorite.

I just want to make sure I’m not missing some other obvious solution.
