October 2011, I started my book project with CALAMUS, a software from 1992 written for ATARI computers running in a Motorola 68000 emulator. After some crashes, I decided to search something more reliable and found Scibus.
Now I finished the English version of my book. (http://calculation-error.org)
404 pages DIN-A5
A 52 page read test is attached at this post.
For the online-shop, I decided for E-Junkie (http://www.e-junkie.com/?r=202501)
I discovered this vendor by asking Google for "How to stamp a PDF".
On each page is the name of the owner, email address and transaction number stamped.
I think far better than DRM.
To make this copyright protection a feature,
make a peronalised gift out of it (http://calculation-error.org/recommend/gift-from-to.htm).
Other important features of the online shop system:
Voucher codes.
So when somebody makes a pre-order for the German version, he receives a voucher code for the English PDF to have something to read until I am ready with the German version.
Or what when somdbody wants PDF and book? He receives a voucher code with the PDF to get the book cheaper.
Voucher Codes can be integrated in Links.
For example, this link contains an US$ 10 voucher code for the PDF useable for the first 5 using it (https://www.e-junkie.com/ecom/gb.php?c=cart&i=1168918&cl=202501&ejc=2&discount_code=SCRIBUS)
