For some reason, I’e seen a number of humorous essays on the art of blurb writing. Blurbs are those quotes about the book authors (or their editors) try to get from authors (or sometimes from experts in the field, or some sort of celebrity). If you are asked to blurb a book, there’s definitely an art to it. I’ve blurbed a few books in my time, but I feel I’m not pithy enough.
Here is a piece of advice from the latest essay, which ran in BN Review:
