The City of Dreaming Books (original title: Die Stadt der Träumenden Bücher) is the fourth novel in the Zamonia series written and illustrated by German author Walter Moers, but the third to be translated into English by John Brownjohn.

Protagonist Optimus Yarnspinner (Hildegunst von Mythenmetz in the German text) is a Lindworm (a species of bibliophile dinosaurs) who inherits a perfectly written manuscript from his mentor.

A publisher directs him to Pfistomefel Smyke (Phistomefel Smeik in the German text), who controls the book trade by means of musical hypnosis.

Smyke pretends to help, but then reveals that he hates art and that a truly gifted author would raise the bar and hurt the market for mass-produced fiction.

Many years ago, he showed his manuscript to Smyke and was transformed into a golem made of an alchemistic paper that is nearly indestructible but will catch fire if exposed to natural light.

Below are a few listed in alphabetical order by the last name of the real-world author: The City of Dreaming Books also contains fictional words, found in most of Moers' work.
