I used to have a gigantic collection of books. Several walls' worth of shelves. Then I moved to another country. Then another. Then another continent.

With each move my collection shrunk until I decided to give up on physical copies. I still have some art books and albums, but for text I stick to DRM-free digital files, for comics - all digital (with a few graphic novel exceptions). Same for music and video - ripped it all into my own server.

Transition took forever and I do miss the smell of paper sometimes, but I no longer have to give away media or look for places based on ability to accommodate my collections.
