There is simply nothing like the physical presence and feel of a paperback. It is still special.
Ebook royalties are massive in comparison however, my mission is to get my books read. With this in mind, I have revised the books I have published on createspace and dropped their prices. This is reflected on the Amazon author page already.
My aim, get these books read. That is all.
Profit margins are secondary and otherwise unimportant.
Hopefully, more readers will access the paperback version of the catalogue and entertain themselves with this portfolio of work.
