In the new books section at my friendly local public library, I just found and read a wonderful little illustrated book by Neil Gaiman from 2018 titled Art Matters (illustrated by Chris Riddell).
On September 6, 2018 The Guardian published one of the essays from it, the 19-page Why Our Future Depends On Libraries, Reading and Daydreaming. That essay came from the 2013 Reading Agency Lecture, which you can find at their web site (as both a YouTube video and a transcript). Compare the transcript with the essay, and you will see the power of editing.
