Microfilm Lasts Half a Millennium
As a kid I got to play with microfilm and microfiche at the library while my mom did research.  I don't have a lot of pleasant memories from childhood, but this was an exception. 
 My mind was intrigued and blown by this.Thinking back on the experience, it was incredible.  I could go grab a copy of a newspaper from any particular day in any year.  I remember reading the actual newspapers from the early 20th century.  Big historical events that are in history books, really take on a different meaning to you when you read them as they were reported in near-real-time.  The ability of microfilm to snapshot history in a way different than say viewing a jpg or png, is fascinating.If you are ever bored, and can find a library that will give you access, you should definitely check it out.  It's an experience I think all hackers should have.  Such simple yet powerful machines, built on a highly non-technical system of convention.  Very cool.  Sorry for the long walk down nostalgia lane.
