While the author of a book needs to be responsible for fact-checking, publishers cannot overlook fact-checkers and just assume that authors have done their research anymore.
In publishing, we have the privilege to breathe life into a book many times over through editing, design, and marketing. We get to guide a manuscript through many transformations and make many choices that affect its future. We decide how the edits will shape the story, how the design will frame it, and how the readers will see it in stores. At the end of all this, a book exists in the world that might not have otherwise.
