Is there a plugin that will maintain a record of ebooks you've shared?

I share certain e-books with my kids. My problem is, any maybe this is a senior moment, but I cannot recall if I have sent a particular e-book or not and I have no record to check. Is there a plugin that will track that information?

I apologize in advance if this was asked and answered, I did search for it, however, using the key words is well, key to getting results!
