Here's how you might download a digital book, depending on where you acquire it:
* From an ebook retailer (e.g., Amazon Kindle, Apple Books, Google Play Books, Kobo): You purchase the ebook, and the retailer provides a method for downloading it to their associated reading app. The app will then sync with the retailer's servers to manage your library. You don't directly download a file in the traditional sense; you're downloading access rights and metadata.
* From a library (e.g., Libby, Hoopla): Many libraries offer ebooks through apps like Libby or Hoopla. You borrow the ebook, and the app downloads a temporary copy to your device. This copy is usually deleted when the loan period expires.
* From a website offering free ebooks (Project Gutenberg, etc.): These websites usually provide download links to files (often in formats like EPUB or MOBI). You'll need an ebook reader app to open these files. Be cautious of websites offering copyright-protected books for free download – these are illegal.
* From a subscription service (e.g., Kindle Unlimited, Scribd): You subscribe to the service and then download the books you wish to read using their app. Access is revoked if the subscription ends.
In short, the process depends entirely on *where* you get the book. The "edition" only tells you which version of the book you want; it doesn't dictate the download process. You need to find a digital version of that specific edition from a reputable source.
