Google Books Downloader
Google Books Downloader is a free application for the Windows and Mac operating system. You need to open the Google Books website in a web browser to copy the web addresses into the downloader. Just head over there and search for books that you would like to download. All that needs to be done afterwards is to copy the web address and paste it into the application afterwards.
I’m sure this could be helpful to some people out there :>
