About TECH BOOK

TECH BOOK publishes focused, practical PDF reference guides for programming languages, frameworks, and tools — 44 topics and counting. Each guide is built to be read in one sitting or kept as a searchable reference, without the time investment of a full course.

Every title is available on its own, or as a single bundle covering the entire catalog — buy once, keep the files, no subscription.
