I came across the following statement by the Chicago University Press:
If your book has its origins in a dissertation, your acknowledgments should not draw attention to this fact, as it will discourage library sales and book review attention.
Why are dissertation-based books looked down upon?
A dissertation-based book is not necessarily of low quality. I was surprised to read such a statement from a respected publisher. Isn't this unprofessional? If there is such a stereotype, shouldn't a publisher like the Chicago University Press refrain from nurturing it?
