This is something that I've used for a while now, and I've been checking up on it recently, and I still enjoy using it.

Do you have a big collection of DVDs, books, music, comics, and video games? Well, now you can keep a database of your collection on your computer. Collectorz.com has different individual software that allows you to register titles you own onto your computer. There also exists cloud-based catalog software on your computer, and those require a yearly subscription.

I have the one designed for Game catalogs, and I love it. The collections are really organized, and I like how it comes with the boxart, description, and a Youtube video.

Seems like a lot of work for no real defined purpose. To me anyways.

I'm trying to remember what site it was, but some member on RJ cataloged every game they were playing and even added anecdotes which I'm sure no one read. I found it fascinating, but for different reasons.
