Yes! Starting September 2020, all books on NetGalley will include a new "Available on NetGalley" section, located just below the book description on the Title Details page.
Every book on NetGalley will display the available File Types (EPUB, MOBI, PDF) and Reading Options (NetGalley Shelf App, Send to Kindle, Download) that the publisher has currently enabled for the book. This section will be visible before, during, and after you request a book.
Please keep in mind that the available File Types and Reading Options may change for a particular book, since it is always at the publisher's discretion to upload new files and enable/disable Reading Options.
