General catalogue of e-books is a curated repository that collects links and resources for freely available technical and programming books, with a focus on high-quality material spanning computer science, programming languages, algorithms, systems, and related fields. Instead of hosting the full texts, the project points to legitimate online sources where books can be read or downloaded, serving as a centralized index for learners and professionals who want to build domain knowledge without paying for expensive textbooks. The repository is organized into categories that help users discover books on specific topics such as operating systems, databases, networking, and artificial intelligence, making exploration easier than manually searching the web.
