The screenshots below are from Google Books, showing the link to the Google eBook version in the blue box to the left, and the formats available for downloading, in the upper right. The “Settings” box in the center is pasted from the Google eBook record, to show the connection between download formats and the versions available in Google eBooks.
In the first example, both PDF and ePub formats available for download in Google Books. Correspondingly, in Google eBooks, Flowing text and Scanned Pages are available.
In the second example, only PDF format available for download in Google Books, and in Google eBooks, only Scanned Pages are available. Note that this is indicated in the blue box in Google Books with the note that the Google eBooks version is “Better for larger screens” (circled in red) – i.e. the PDF version is not good for mobile devices.
