How Reporting Errata Helps
Errata that is submitted on oreilly.com becomes visible on the site immediately, so it may be helpful to other readers or viewers who encounter the same problem. Submitted errata is reviewed by O'Reilly or the author, and confirmed errors are corrected in electronic versions and future printings of a book.
