Doomsday For a Book Hoarder

I love books and have since I first learned to read, maybe before. The library was a second home and still is.
Once I got an apartment then a house, I became a book hoarder. My present house has eight full four by six foot bookcases plus a couple of smaller ones filled. Maybe one doesn't count as it's full of reference books. There are six three foot stacks of books next to my computer space.
Some time back there was a blog post about hoarding books. It boiled down to every book sitting gathering dust on a shelf was one no one else could read.
My book hoarding soul took note. I looked over my shelves. I took piles sitting on top of bookcases down. Several boxes of books left.
Except I got these books to read. I do want to read them - someday soon. I wonder how long it will take me to read through a couple thousand books at even a hundred a year.
I am making progress.
That progress is in peril. My partially reformed book hoarder soul is doomed.
There are TWO library book sales this weekend!
I am determined. I will NOT bring home more than 15 new books from these sales.
Please note this means reading books only. Reference books are exempt from this limit. I did clear some shelf space off for botany reference books. Empty space on a book shelf begs for books.
My hoarder soul is trying to reform.
