I am sharing Reedsy’s blog post on copyrighting a book because this is a question people ask regularly. I recommend reading both posts in this series. The first post outlines the mechanics of obtaining a copyright from the U.S. Copyright Office while the second discusses other important details. Among those details in the second is the following:
“Copyright exists as soon as the words are written
Copyright protection on an original work exists in the United States and the United Kingdom the moment you create that work (and extends for 70 years after your death).”
Thank you, Reedsy, for this informative post which you can find at How To Copyright a Book: A Definitive Guide.
