Abstract :
With the increasing interest in automata theory, the number of books on this subject has been steadily increasing since the early 1960´s. Depending on the audience, one can now choose books in the graduate level as well as in the introductory junior-senior level. Depending on the emphasis, one can also choose books that approach the subject from different angles. This book, Abstract Automata, by P. H. Starke of Germany is certainly a welcome addition to this collection.
