The Essential Reader's Companion is a third-generation Essential Guide written by Pablo Hidalgo, and published by Del Rey. In July 2010, Sue Rostoni posted an updated publishing calendar with this book having been pushed back to March 20, 2012. In December 2011, the book was mentioned to be pushed back again to a release date of August 21, 2012. On March 19, it was announced on Facebook that the release date was moved back to October 2 for the art team to finish more paintings.

At Celebration V it was announced the book would contain summaries of all novels, young readers books, and novellas, listed chronologically by their in-universe setting, as well as behind-the-scenes information and brand-new illustrations, specifically the long-awaited picture of Cal Omas.

Unlike recent previous entries in the Essential Guide series, The Essential Reader's Companion is presented from an out-of-universe, or "real-world," perspective, rather than as a piece of in-universe writing.
