The one marked as "Economy Edition" is grey color version with grey color images and the other one is a full colored version. They are identical except for this difference.
I have made them different so that readers can have a lower priced version. The color does not make much difference since the contents don't assume color. It is only for better readability.
Hi Dr.King
ReplyDeleteI see that you have two versions of the same paperback. What are these meant to be?
