An embarrassingly high count has yet to be completed.
I currently have over 4000 listed and a many more I am still adding as I list my books I own. There are SO many books I want to read. Many are series' so those can add up fast but it varies greatly what I have listed. I am hoping that by the end of this year, my list of books I own is complete so so that adding books to my TBR starts to stabilize and that in 2015 I can actually start to make progress toward lowering that number over time. Yet it will be high for many years. After all, there are still wonderful books I have yet to hear of, and even more that have yet to be written.
