I bought You Share Good by Gwenn Seemel and read it in almost one sitting. Gwenn’s argument for letting go of copyright and relaxing into sharing is persuasive, and I highly recommend it — even if you choose to copyright any part of your work, at least you will be aware of what you are doing!
“Since 2009, I have not claimed the copyright on any of my art. This book is about why I decided to do that and why you might want to as well, and it also covers the how-to part of freeing your art.”
You Share Good is a digital book. You can read You Share Good here for FREE.
There’s also a downloadable PDF version of the book available for $4. I bought mine!
