Yeah you, I'm talking to you geek. How many dusty old college textbooks do you have stuffed away in the attic or in your office putting on an aura of pseudo-importance? How many times have you tried to part with said books but can't relinquesh them due to 1.) The huge investement they represent, 2.) The money it will take to dispose of them 3.) A sense that they will end up clogging a landfill 4.) Some notion that you'll actually read them and learn all the stuff you copied in college?
Here is you chance. Go here, get a shipping lable and donate them.
Make the world a little better today. Clean out your attic and donate a book.
But please hang on to that copy of Supersystem. You need it.
