Risks of using unauthorized PDFs
A significant number of engineers, particularly students and those early in their careers, search for free PDF versions of technical books online. GitHub, as a public platform for sharing code and documents, has historically been a location where such files are uploaded, sometimes without the copyright holder's permission.
