Aho/Ullman Foundations of Computer Science

Abstraction: Free classic CS theory textbook by Aho and Ullman, out of print since 1992

Key points:

• Originally published 1992 by W. H. Freeman; taken out of print but made freely available online by the authors.
• Co-authored by Alfred Aho and Jeffrey Ullman (Stanford); intended as an introduction to CS theory.
• Gradiance automated homework system offered free trials for instructors and students through the book's exercises; the student open-enrollment class code was 8CD5ED01 (active until 2009).
• Authors still believe (as of the page's writing) this is the right way to introduce theoretical CS.
