Re: School yearbooks. What a waste. 
aah c’mon Mirch bhai - Yearbooks are mementos of past times… keepsakes to remind people of good times and bad, their friends and foes, their follies and craziness, and all that was amusing in one’s carefree days.
I agree in that they can prolly be digitized, and in fact, my brothers had theirs as a flash e-Book CD from their high school. That being said, it is often argued that digital just doesn’t cut it. It’s the same sort of thing as with picture albums of your momentous occasions, and I’m sure most of us cherish the photo albums of engagements, weddings, and birthdays… more than their digital counterparts.
