Organize MYOs

How does everyone organize your MYO tracks for the same character? For example, I have a bunch of Disney. The storyteller versions, junior novels, songs and stories, etc. for a lot of characters. Do you put each type on a separate card? My little one is just about to turn 4 so not quiiiite old enough for an independent library system (we do have the set up with the interchangeable type of stickers on the cards though for when she’s ready).
