I buy a lot of books from Amazon (EU). Recently, more and more of the books I received were printed by Amazon themselves with the message "Printed in Poland by Amazon Fulfillment" on the last page.
They are of decent quality, though sometimes the cover art might be lower-resolution than that of an equivalent book from a bookshop. I double checked and all of these were sold by Amazon themselves (i.e., not a marketplace seller, where I would suspect a piracy issue). The cover material is always this unpleasant matte rough-feeling paper.
Is there anything nefarious going on here? Does Amazon have permission from the publishers to distribute their books like this? The books that I received were of different publishers (Penguin, Basic Books, among others).
I bought another self-published book that was also print-on-demand. The larger font size made it readable although the font weight makes the footnotes look quite bad.
I wish Amazon would show on the product listing that it's a print-on-demand book since they're inferior to traditionally printed books with the equipment currently being used.
