21 Free Data Science Books

Last updated July 24, 2020

To help people exploring the data science career track, I've taken some time to compile my top recommendations of quality data science books that are either available for free (legally, of course) or are Pay What You Want (PWYW) with $0 minimum. I include the last updated date of the book in parentheses.

If you did enjoy the book, there are usually options to purchase a hard-copy of the book to support the authors.

During COVID-19, Springer has also released a large number of its textbooks for free.
