Operating System Concepts

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. The idea was that like dinosaurs, operating systems evolve.

The book has been published in updated editions since 1983. The third edition added the author Peter Galvin, and the sixth edition added the author Greg Gagne. the textbook was in its ninth edition.
