Edition History and Reception
The forerunner of this book appeared under the title Formal Languages and Their Relation to Automata in 1968. Forming a basis both for the creation of courses on the topic, as well as for further research, that book shaped the field of automata theory for over a decade, cf. (Hopcroft 1989).

The first edition of Introduction to Automata Theory, Languages, and Computation was published in 1979, the second edition in November 2000, and the third edition appeared in February 2006. Since the second edition, Rajeev Motwani has joined Hopcroft and Ullman as third author. Starting with the second edition, the book features extended coverage of examples where automata theory is applied, whereas large parts of more advanced theory were taken out. While this makes the second and third editions more accessible to beginners, it makes it less suited for more advanced courses. The new bias away from theory is not seen positive by all: As Shallit quotes one professor, "they have removed all good parts." (Shallit 2008).
The first edition in turn constituted a major revision of a previous textbook also written by Hopcroft and Ullman, entitled Formal Languages and Their Relation to Automata. It was published in 1968 and is referred to in the introduction of the 1979 edition. In a personal historical note regarding the 1968 book, Hopcroft states: "Perhaps the success of the book came from our efforts to present the essence of each proof before actually giving the proof" (Hopcroft 1989). Compared with the forerunner book, the 1979 edition was expanded, and the material was reworked to make it more accessible to students, cf. (Hopcroft 1989). This gearing towards understandability at the price of succinctness was not seen positive by all. As Hopcroft reports on feedback to the overhauled 1979 edition: "It seems that our attempts to lower the level of our presentation for the benefit of students by including more detail and explanations had an adverse effect on the faculty, who then had to sift through the added material to outline and prepare their lectures" (Hopcroft 1989).
Still, the most cited edition of the book is apparently the 1979 edition: According to the website CiteSeerX, over 3000 scientific papers freely available online cite this edition of the book (CiteSeerX, 2009).
