Choosing a free culture license ensures your work can be shared easily and fairly, for any purpose.



By default, international copyright law restricts sharing. Each person who wants to share your work must get your permission. Using a free culture license is a way to give permission proactively.

Why bother?

If you curate or take part in a sharing community, it is advisable to use and encourage others to use licenses that enable reuse. Informal sharing isn't hindered by these technicalities, but when someone wants to distribute widely, modify wildly, collaborate, or reuse for a profit, these technicalities become very important. Without an appropriate license, the easiest path would be to not include your work, which kind of misses the point of sharing it in the first place.
