Reading lists

I've got this horrible problem, where I develop over time a huge list of books I have to get around to reading.  I've got a shelf of them right now.  And, for the most part, I don't. That's not to say I don't read.  (Though I do go through pretty significant dry spells sometimes.)  But I somewhat rarely get around to reading the books that are actually on my shelf.

I'm beginning to wonder whether it might be a problem with the mechanism of reading lists/shelves themselves.  I think I might be using the wrong decision making mechanisms to choose what books to read.  Or, rather, the criteria by which I choose to read a book are out of sync with the criteria with which I put books on the to-read shelf.

On the other hand, it might just be representative of the continual triumph of my impulsive self over my more measured self-interest.  The Corrections has been sitting on my to-read shelf for about four months now, but it took me no time at all to get to Reality Is Broken.

Thoughts?
