I want to publish a printed books and ebooks in Arabic language. Is that possible on websites like lulu.com and amazon.com? If yes what are the conditons for that? I am sorry for my broken english.
You can publish in any language you like, but you will have the problem with books that read from the 'back', mainly with the covers.
Also, I think with ePubs with ISBNs, Apple will only allow them from Lulu in English, apparently.
There are Arabic books on Amazon but none seem to have a Preview and that is perhaps because they start at the 'back'.
