100+ Free Science and Math Textbooks and Lecture Notes

textbooks

Textbooks are among the best ways to familiarize yourself with a subject. However, they can sometimes be expensive. Fortunately, there are various freely available textbooks online. They may not cover everything that textbooks that cost money do and they may not be as reliable, detailed or as prestigious, but they can serve as a viable introduction for curious individuals. Therefore, I cannot guarantee that every book in this list is 100% accurate, but I try to pick reputable textbooks. I have not included very old textbooks (although be careful with trusting older books too much), or certain open access textbooks that promote pseudoscience like alternative medicine in some of its chapters. I have also not included textbooks that have been uploaded illegally. In other words, all of the textbooks in this thread can be read or obtained legally. Finally, some of these “textbooks” are actually comprehensive lecture notes, so please count them as functional textbooks.

Note: There are probably hundreds more of this stuff out there on the Internet. However, there comes a time when I might as well publish the list of the ones that I have so far, as this will always be a work in progress. Enjoy.

Note: See a textbook or set of lecture notes that is missing from this list? Post your discovery in the comment section and I’ll add it to the list, without attribution, if it makes sense.

    Wow! Excellent compilation of resources. I also use free textbooks a lot to learn about things that interest me. I’ve usually seen math and physics ones. Didn’t know there are ones for biology too. That’s awesome. I’m currently slogging my way through a linear algebra textbook (Elementary Linear Algebra but Kuttler [ironically from Brigham Young University]; and not exactly easy to read; I wouldn’t recommend it to others, but it was the first one I tried).

    I got turned off from math (specifically calculus and linear algebra) in university (most people unfortunately get turned off much earlier), but since I’m trying to learn about Bayesian statistics/probability, it’s become clear to me that I was missing key skills which I had forgotten or never picked up. It was daunting to start, but I’ve found, rather surprisingly, that I really fricking enjoy it! It seems to me that learning on one’s own, at one’s own pace, is far more enjoyable than trying to learn in the typical North American school system (I imagine it’s probably similar in other countries). I’m am now truly fascinated by calculus and linear algebra, the two subjects that I had most disliked earlier. It is a tragedy that the way these subjects are taught leads the vast majority of people to dislike or even hate them. I’m sure it’s true of the sciences too.

    Thanks for posting this information for other folks to find. It is invaluable! :-)
