Copyright is meant to do something— several things— to accomplish
socially desirable ends. One of those ends is to create a space for a free
exchange of ideas that allows us to build upon a universe of expression
that came before. The world is a rich place because of authors, and it is
enriched further by works of authorship in the public domain that anyone
can copy, rearrange, and repurpose in any way they choose. This
toolkit is an example of the tremendous work that can be accomplished
when we are free to build on what has come before.
