Download Springer Free Ebooks

Springer Publications has recently released a huge list of books that are now free to access, Let's grab download links for them.

Ebook links

List of books is available as an google sheet. you can also use this repository to download them. but, it's a python script to download them and is probably slow and as far as I checked is not using download managers like aria2, so I decided to grab the download links automatically and download them using IDM.
