If history is your thing you might want to look into this when you have some free time. 

The Library of Congress is crowdsourcing some of their grunt work. They're looking for people to log on to their website and transcribe some of the nations important documents into a digital form.

MentalFloss - The goal is to digitize these documents, many of which are hard for computers to read, so that they become keyword-searchable. Some of the letters are faded and written in heavily slanted cursive, so volunteers may need to have a good eye to decipher the handwriting. More than 40,000 documents and letters were written by or to Abraham Lincoln alone, and the library is hoping to have 10,000 images transcribed by the end of this year. New material will continually be added to site, including documents associated with Rosa Parks, the woman’s suffrage movement, American poets, and the history of psychiatry.

I've checked it out already and it's pretty cool. It's a nice way to learn a little bit of history plus you're helping preserve and digitize these documents for generations to come.
