Check out "Haldeman-Julius: Pocket Series and the Little Blue Books"

[Scot Kamins]

Folks,

If you haven't discovered it yet, check out the website at:

http://www.haldeman-julius.org/

In its own words, it's "devoted to the history, identification and
collecting of the various 3½ × 5 inch volumes published by Emanuel
Haldeman-Julius (and his son) via Appeal to Reason, Appeal Publishing
Company, Haldeman-Julius Company, Haldeman-Julius Publications, and
The Little Blue Book Company."

Nicely designed, too!!!
