Sheldon Axler's 'Linear Algebra Done Right,' 4th edition (August 2026) is now open access under Creative Commons BY-NC, with free PDFs in English, Chinese, Farsi, Greek, and Portuguese. The 4th edition adds over 250 new exercises and 70 new examples, and continues its distinctive approach of deferring determinants to the end while focusing on linear operators on finite-dimensional vector spaces.

Why: If you're an AI/ML learner or practitioner who wants to strengthen linear algebra foundations—eigenvectors, SVD, spectral theorem—this is a respected, now-free textbook you can download immediately instead of paying for the Springer print version. The determinant-free pedagogical approach may suit those who found traditional treatments unmotivating.
