About free supporting fields books
This category collects 111 legally free supporting fields books from the recovered FreeTechBooks catalog. Each record includes the author, publisher, publication year, license and a direct link to the source that hosts the book.
The list mixes foundational textbooks, course notes and practical handbooks. Some are published by universities or open-textbook initiatives; others are self-published by their authors. Use the license filter if you need a title you can remix or redistribute, and check the license page before reusing a book in a course or project.
If a link no longer works, open the book page and use the archived copy when available, or report the broken link so we can verify it.
