My friend told me that he has found a great selection of free eBooks on the website www.tuebl.ca. He told me that almost all of the books were free and the authors didn’t remove anything from the website. I went to the website and downloaded the eBook, and it wasn’t mentioned the price, so I thought that it was for free. But when I pressed “to download”, the website showed the icon, where I needed to choose the way of payment. So, be careful.
