San Francisco Chronicle - (Sunday)
Inside the newsroom
Anonymous sources: The Chronicle strives to attribute all information we report to credible, reliable, identifiable sources. Presenting information from an anonymous source occurs extremely rarely, and only when that information is considered crucially important and all other on-the-record options have been exhausted. In such cases, The Chronicle has complete knowledge of the unnamed person’s identity and of how that person is in position to know the information. The Chronicle’s detailed policy governing the use of such sources, including the use of pseudonyms, is available on SFChronicle.com.
