Best Free eBook Download Sites – Continuous Updates

There was a time when I bought my first Kindle and I collected a list of websites to download free eBooks. When I see it again, some of the websites have already stopped operations or there are errors itself. So when I start writing this post, I decide to update regularly and make sure readers can easily find the best free eBook download sites that actually work.

If there are other great websites for downloading free books without registration, welcome to leave a comment below.

Library Genesis

Library Genesis is probably the most famous and one of the most well-stocked free eBook download sites. It can sort papers/eBooks neatly. Search a book on this site, you might find several versions of the book, and you can download according to your needs. At the far right of each entry, there are five mirrors to select. Mirror [1] is unlimited for download. LIBGEN, ZLibrary, and BookFI are all mirror sites.
