Check out this post from Michael Dirda as he talks about the problems of a particular kind of addiction — books! Are you one of those notorious book hoarders too?
From the American Scholar article:
Now this is bad, very bad. These days I can hardly step away from this desk and not find myself gravitating to a used-book store and pulling out my credit card. I can almost always justify my purchases as sensible, reasonable courses of action. All addicts do this.
Incidentally, Michael Dirda will be visiting GWU soon for his UHP-sponsored talk on Sherlock Holmes.
