I have a very small library of about 150 books that I am really proud of. I'm proud of it because I started building it while still taking an allowance from my parents. But I'm also running out of space and I find that technical books become obsolete in a matter of months. So I stopped buying books that talk about frameworks and such and now only stick to the classics that won't lose value unless the technology substantially changes. Others, I now purchase in a digital format.(I have a Sony ebook reader) Digitization is one approach, but I am too attached to the books to destroy them. And I agree with the sentiment of the article, it's just not the same.
