Operating System Concepts by Abraham Silberschatz and James Peterson is a classic textbook on operating systems. It is often called the "dinosaur book", as the first edition of the book had on the cover a number of dinosaurs labeled with various old operating systems. The bigger dinosaurs were labeled with the older big OSs. The ape-like creature was labeled UNIX.{{cite web|url=http://codex.cs.yale.edu/avi/os-book/OS9/covers-dir/index.html|title= Covers of Previous Editions |website=codex.cs.yale.edu}} The idea was that like dinosaurs, operating systems evolve.{{Cite web|url=https://galvin.info/history-of-operating-system-concepts-textbook/|title=History of Operating System Concepts Textbook|date=March 21, 2013|website=galvin.info}}
