Could You Do It?

Okay I've gotten to the point where my books are being shoved every which way on my shelves cause I have no more room. I've decided it's time to condense but don't know if I can do it. There are authors that I know are good, I've heard great things about but just haven't read. I have books by these authors but they just don't appeal to me, or they do appeal but I just don't get to them. Whatever the reason. I really want to be able to get rid of them but I just can't seem to let go. Why? Because I keep thinking, one day I might want to read them. One day, then I'll be mad I got rid of them.

If I got rid of them I'd clear up this entire space.
So here are some of the authors:
Stephen King
James Patterson (I've read two of his but they were the lighter ones; Suzanne's Diary to Nicholas and Letters to Jennifer)
Dean Koontz
Robin Cook
Belva Plain
Mary Higgins Clark
Joanna Lindsey
Elizabeth Lowell
Tami Hoag
Tessa Gerritsen

I don't even know if I spelt half of their names right.

So what do you think? Should I get rid of them? Should I keep them??? What to do what to do. If any of them are really really great tell me and I'll try them. But they've just been sitting there for like 2 years. Something needs to be done.

I know that picture is all huge but I wanted you to get the full effect. Actually I was to lazy to make it smaller. Whichever.
