A quick search of the internet reveals a plethora of books for programmers. No one has time to read even a minuscule fraction of the available books.
What you need is a curated list of programming books. Better than that. A curated list of free programming books. Free and open source books still have a cost — your precious time. And just because a book is free/open source doesn’t, itself, signify any great quality to the work. Hence the need for some recommendations for free books to help you learn C, C++, Java, Python, R, or whatever language takes your fancy.
The books we’re recommending will help increase your technical skills and make you proficient in the language of your choice. And some of them even provide a little light relief on the way. Humor can be a great aid to learning.
Many of the books we recommend offer a solid foundation in learning the relevant programming language. Some are very specialist, some offer a quick overview. There are books targeted at people who have zero programming experience, as well as programmers who have learned one or two languages but are looking to widen their skills. Other books are targeted at an intermediate and/or expert level. All are worth reading.
Some of the books are available to purchase in printed form. Showing your support in this way can be a great motivation for the authors to carry on releasing free books.
The series is expanding although it’s pretty comprehensive already. And we’re adding new languages, so remember to bookmark this page.
