When was the last time... you looked for a number in yellow pages?

Photo from here.

When was the last time you referred to a directory such as Bell's or Yellow Pages?  I could not remember either.  Printing old school directories is a dying business now that every one refers to the internet to search for people, addresses, numbers and all other things.  Printing humongous directories such as these that end up in either the attic or garbage is a waste of resources.  

Save the trees people.
