Free Books, Courtesy of Springer

Springer, has announced some days ago, that they are making available plenty of their books (aimed at higher education) for free during the coronavirus pandemic. "These books will be available via SpringerLink until at least the end of July." Take a look at the announcement and at the list of the texts available in english and german.

If you are going to download some of them, I encourage you to obtain them as .epub, since it is more space efficient than pdf.
