This paperback has been requested by the author: https://ebookmovil.com/amila-arturo-m.... According to that webpage (publisher site) the book is only available as a direct purchase via email/whatsapp (so I understand we shouldn't add it to the database) at the moment, but it will be available in bookstores and major e-commerce sites 20 days after release date. Can I add it now or should I wait until it's available everywhere, just in case? Also, what about the release date?
I would go ahead and add it along with its ISBN/ASIN since we know when it will be published. The release date should be when the book becomes available to people *without* emailing or using what's app (in my opinion). Others may feel differently.
Also, what about the release date?
