☛ Authors may choose how and by whom their works are copied, distributed, or otherwise made available to the public.
Copyright gives you control over the distribution of your work, in any and all channels and media.
There are "fair use" exceptions for small portions, for certain purposes, and the Authors Guild believes in the importance of the fair-use doctrine. But, for example, if an academic institution makes an electronic copy of your entire book freely available, this is a violation of copyright. It’s illegal unless you give him permission. When in doubt, ask us. We’re here to support you.
