Report on or about?


In the following sentence, which preposition is correct, on or about?

  • I am writing a report on/about art.


As it turns out, both on and about are correct. The Canadian Oxford Dictionary (2004) says that the preposition on can mean concerning or about. For example:

  • Leia enjoys documentaries on (or about) whales.

In fact, all of the sources consulted list on and about as synonyms in this context.
