Thanks everyone !
Curtis - lulu used to offer the option to purchase a bound version, but they have changed a lot since, for example, I placed my Demos coins book on lulu a few years ago.
In fact lulu has changed a lot - the Demos book was simply converted from my old Word (which I
still used) to a pdf using dopdf, uploaded, a couple of options marked and that was it.
Now, lulu require all fonts to be embedded, all page the same size (which is why the original
Bernhart plates are not so
sharp as my own plates, because I
had to resize those pages), and some other changes to be made.
I did not select the option to add it as an epub, Kindle thing etc because they wanted one form to be filled in and stamped by my local tax office and another form filled in for their own tax people for payments abroad, and some other declarations and legal stuff, plus I would have
had to grant them worldwide exclusive licensing rights, which I did not want to do.
