Other than the souls of small children, what do you collect?

Signet Classic paperback books, Money (bills or coins, old or new, foreign or domestic), postcards, vital records on my ancestors (for genealogy), digital music and photos, CDs & DVDs, and many many more things. But I'm trying to stop now. Less clutter is a good thing. My new image is minimalism. Media formats keep changing anyway. I've been developing all my digital photos too... WOW!!
