Textbook of advertising. Many theories work for more than publishing products in a general market. They can be used for publishing knowledge.

Quite overrated in my opinion, it did not stand the test of time very well as it offers lots of specific advice which tend to make less sense in the digital age, and are more relevant for printed letters.

There is still some useful tidbit of knowledge and the book is around 60 pages long, so it can be worth a read, but I did find it somewhat boring and I didn't come out of it with much that isn't already common knowledge.
