For a listing of all the currently available secondary REH reference works go to https://rehfpress.com/secondary/.

These volumes are intended to aid the REH scholar to see more details about REH’s life, his friends and family, and unusual items of potential interest. Many of these volumes were compiled by REH scholar Rob Roehm.

All secondary reference volumes are available as either trade paperback or hardcover. This series is unlimited, though on occasion contents are updated as new material is located. None of these books are sold through this website so follow the links to each volume and it will take you to Lulu.com where these books are printed on demand.
