## BY PROGRAMMING LANGUAGE
Originally, this list included a section called "Language Agnostic" for books about programming subjects not restricted to a specific programming language.
That section got so big, we decided to split it into its own file, the [BY SUBJECT file](free-programming-books-subjects.md).
