Good luck! I know your pain. I've been reading a lot from the library myself and have discovered that I own over a 1,000 books and I don't know which ones I have read and which ones I haven't!
Maybe you could borrow your owned books from the library and read them that way, or borrow some audio books for some of the ones that you own and listen to them on your way to work and start taking down your TBR that way.
