This is my to-read shelf. As you can see, it's two rows deep. Some of the books have been there an embarrassingly long time. I did cull the shelf recently getting rid of those I doubt I will read... but when I keep borrowing library books and those have due dates I tend to read them first. Every now and then one of these books gets read though... the gaps in the shelf don't last though.
I'm sure they will get read some day. These books are amongst the larger items on my longer term to-do list.
