<human>: I have been building a library for a few years now. My goal is not to collect first edition or rare books, so I mostly have paperbacks.  All the same, I treasure my books, and I would like them to outlive me if possible.  I'm a fairly messy guy, when I'm actually reading a book, so my books often end up looking a little ruddy, but I was wondering, how long will my book collection last?  I would like my books to outlive me, or to last until I die at least.  Should I start purchasing hardcover editions, or will paperbacks do with proper care?  

Any advice would be great.  

Love,

Can you condense the text into three sentences or less?
