Only one of these five books is clearly confirmed as a free, complete, open-access book: Julia Data Science. The others may offer a free extract, conditional institutional access, or a route to purchase, but the available official information does not establish universal free access to their full text. Use this guide to choose by your learning goal—and check the access terms before settling in.
How to choose among these Julia books
The five titles appeared in a June 15, 2023 roundup. Because access can change, its “free” label should not be taken as proof that every complete book remains available at no cost. The comparison below separates each book’s learning focus from what its official access information supports.
| Book | Best fit | Main emphasis | Access supported by the cited sources |
|---|---|---|---|
| Think Julia: How to Think Like a Computer Scientist | New Julia learners and programmers seeking foundations | Language concepts and exercises | The 2023 roundup linked it as a free book, but current official full-book access was not independently verified. [KDnuggets roundup] |
| Julia as a Second Language | Programmers who already know another language | Julia programming, including data-science context | Manning identifies a free extract; free access to the complete book is not established. [Manning book page] |
| Statistics with Julia | Readers studying statistics or applying Julia to statistics and machine learning | Statistics, machine learning, and data science | The authors describe possible university access through SpringerLink and purchase options; universal free access is not established. [Official book site] |
| Julia Data Science | Data-science learners and applied researchers | Julia basics, data handling, and visualization | Open access online and as a PDF. The site displays a CC BY-NC-SA 4.0 license. [Official book site] |
| Julia for Data Analysis | Readers seeking practical analysis workflows | Data formats, tabular operations, visualization, predictive models, pipelines, and web services | Manning lists the commercial book and Manning Online access; its free extract does not establish free full-book access.

The five books, in detail
1. Think Julia: How to Think Like a Computer Scientist
Ben Lauwens and Allen B. Downey’s book is the foundations-oriented option. The roundup describes it as a broad introduction for beginners as well as experienced programmers, with examples and exercises and topics including arrays, matrices, input/output, metaprogramming, and parallel computing. That breadth makes it a candidate for readers who want to learn the language itself rather than jump straight into a single data-science workflow.
The roundup links to it as a free book, but current official evidence reviewed for this guide does not confirm that the complete edition is available free of charge. Check the linked edition and its access terms before relying on it as a no-cost full-text resource. [KDnuggets roundup]

#1 Best Overall
2. Julia as a Second Language
Erik Engheim’s book is aimed at readers who already program in another language and want to learn Julia. It is the most natural starting point here if you have programming experience but are new to Julia’s approach and syntax.
Manning’s page identifies the available sample as a “free extract.” That is useful for previewing the book, but it does not establish that the whole book is free. [Manning book page]
3. Statistics with Julia: Fundamentals for Data Science, Machine Learning and Artificial Intelligence
Yoni Nazarathy and Hayden Klok’s book centers on statistical concepts and connects them to data science, machine learning, and artificial intelligence using Julia. Choose it when statistics is the subject you need to learn, rather than simply a tool you want to apply through general Julia programming.
The authors say university-affiliated readers may be able to access the book through SpringerLink in some cases. They also point to purchase options and note that they do not control Springer’s price. Treat institutional access as conditional, not as a guarantee of free access. [Official book site]

By Jose Storopoli, Rik Huijzer, and Lazaro Alonso, this is the clearest choice if you need a complete book that is confirmed to be available without payment. The official site describes it as open source and open access and provides both a readable online edition and a PDF. Its stated scope covers Julia fundamentals and practical data-science topics.
The site gives the citation Storopoli, Huijzer and Alonso (2021), Julia Data Science, ISBN 9798489859165. It displays a CC BY-NC-SA 4.0 license: the book is openly accessible, but reuse is subject to the license’s conditions, including noncommercial use and sharing adaptations under the same license.

Rank #4
5. Julia for Data Analysis
Bogumił Kamiński’s book focuses on practical analysis work: reading and writing data in different formats, operating on tabular data, visualization, predictive models, pipelines, web services, and writing readable Julia programs. It is a good match for readers who want to follow applied workflows rather than focus primarily on language fundamentals or statistical theory.
Manning lists it as a 472-page publication from December 2022, ISBN 9781633439368, and says it is included with Manning Online. Manning’s separate welcome page exposes a free extract and directs readers toward buying the book or subscribing. Neither the extract nor subscription inclusion means the complete book is universally free. [Manning book page] [Manning extract page]
Best Value
Which one should you start with?
- Want a confirmed free full book? Start with Julia Data Science, which has online and PDF editions.
- Already know another programming language? Preview Julia as a Second Language; the confirmed free offering is an extract.
- Need statistics or machine-learning foundations? Consider Statistics with Julia, checking whether your institution provides access.
- Want hands-on analysis workflows? Compare Julia for Data Analysis with the applied sections of Julia Data Science, and verify full-book access before choosing.
- Need broad programming foundations? Think Julia may fit, but confirm that the edition you find is available in full at no cost.
A free alternative if the complete book must cost nothing
If you require a full resource that is explicitly described as freely available, the Julia language project’s book catalogue lists Stanley H. Chan’s Intro to Probability for Data Science. The catalogue says it is available as HTML and PDF, with code in Julia, Python, R, and Matlab. It is a probability-focused alternative, not a replacement for a general Julia programming book.
