It turns out that an eerie type of chaos can lurk just behind a facade of order  and yet, deep inside the chaos lurks an even eerier type of order  Douglas Hofstadter.
I realize that it is difficult and frustrating when one tries to tackle a new subject,
especially one as multifaceted and crossdisciplinary as the field of chaotic dynamics.
I know; I was there once  awed by the immensity and complexity of the subject.
Heck, I am still there, wideeyed and all! In any case, I hope the following list of
books will help you on your way to being enlightened. Feel free to email me any
worthwhile additions and/or corrections at lpoon@chaos.umd.edu.
Help!
I try to keep up with the influx of new
books, but I can't do it by myself. After several requests for inclusion of more
specialized texts, I have hit upon a possible solution.
Instead of trying to keep up with all the new chaos books, I welcome submissions
from people who feel strongly and positively about any particular book. I would
appreciate it if the submission includes a short review that points out the
various aspects of the book (eg. good points, bad points, intended audience, etc.)
Submissions in the more specialized areas are especially welcome. I can't promise
to accept all submissions, but if I do, I will give the proper acknowledgments.
Direct your submissions to lpoon@chaos.umd.edu. Thanks!
For your convenience, I have further subdivided the works into several broad categories:

Good Starting Points
 Alligood, K.T., Sauer, T., and Yorke, J.A.
CHAOS: An Introduction to Dynamical Systems, SpringerVerlag, expected in June of 1996.
 A very readable introductory text that is designed for students in mathematics and the sciences (undergraduate to beginning graduate level). The book gives a clear and intuitive presentation of the topics and also illustrates the concepts using selected physical experiments in the "Lab Visits" sections. All the important concepts in discrete (iterated maps) and continuous (differential equations) dynamical systems are covered in a careful and detailed manner. Unlike other introductory texts, it does not shy away from presenting deep and important theorems like the PoincaréBendixson Theorem, Stable Manifold Theorem, and the Cascade Theorem. In addition to explaining its importance, it delves into the heart of the theorems by looking at the proofs. There is nothing like working through a difficult problem by oneself to get a handle on the concepts, and the "Challenge" sections in the book do just that by letting the reader tackle challenging problems from dynamics. Don't worry, one is guided along the way with many helpful hints. Of course, the importance of chaos would not have been widely appreciated if not for computer simulations, thus the book has "Computer Experiments" sections which guide the reader in exploring the dynamics on computers.
Undergraduate Level.
 Baker, G. L., and Gollub, J. P.,
Chaotic Dynamics, Cambridge University Press, 1990.
 An
introductory text that is designed for undergraduates and science
teachers. Using a forced damped pendulum as a model, many basic
features of chaotic dynamics are presented though not indepth.
Lower Undergraduate Level.
 Devaney, Robert L.,
Chaos, Fractals and Dynamics:Computer Experiments in Mathematics, AddisonWesley, 1990.

This is a nice little book whose target audience is high school students, beginning
undergraduates, and science teachers. Using many examples , Devaney leads the reader through ideas of iteration and dynamical system. The latter half of the book deals with the connection between chaos and the science of fractals. The readers are encouraged to explore the various facets of chaos and fractals using simple computer programs (many sample source codes are peppered throughout the book). In addition to the book, there is a couple of companion video tapes that are also highly instructive and serve as good introduction to chaos and fractals. The first video, Chaos, Fractals and Dynamics, bears the same name as the book and brings to life many of the examples mentioned in the book in a manner that is not possible via the static book format. The visual highlight occurs when Devaney shows beautiful animations of the Julia set. If this doesn't get the students excited, I don't know what will! The second video, Transition to Chaos, describes the perioddoubling approach to chaos using the now standard quadratic map. There is a nice discussion about the relationship between the perioddoubling bifurcation and the Mandelbrot and Julia sets. The book and the tapes are offered by Science TV as a set, more precisely, the Chaos Set.
High School and Lower Undergraduate Level.
 Gulick, Denny,
Encounters with chaos, McGrawHill, 1992.
 A very readable introduction for students with moderate calculus background.
Lower Undergraduate Level.
 Gutzwiller, Martin. C., Chaos in Classical and Quantum Mechanics, SpringerVerlag, 1990.
 This is a very nice textbook for people interested in the connection between classical mechanics and quantum mechanics. Students of quantum chaos should definitely have a copy of this on their bookshelf! Graduate Level.
 Hilborn, Robert C.,
Chaos and Nonlinear Dynamics, Oxford University Press, 1994.
 This is a nice hefty chaos that text does a good job of giving readers
physical insights underlying many of the phenonmena and concepts. Another nice
feature of the book is
the annotated bibliography at the end of each chapter which serves as a nice starting
point for further exploration into the world of chaos. And finally, a book that
presents a detailed sketch of how Lorenz obtained the Lorenz equations! (Appendix C)
Upper Undergraduate Level
 Jackson, E. Atlee,
Perspectives of Nonlinear Dynamics, Vols. 1 2, Cambridge University Press, 1989.
 An ambitious text that is chockfull of topics and diagrams. Its breadth of topics is a
drawback when one considers using it as an introductory text since the book is very loosely
organized in terms of logical structure. However, the twovolume set makes excellent
supplementary texts. In addition, it has a very extensive bibliography section that is also
referenced by topics. Graduate Level.
 Kaplan, Daniel, and Glass, Leon Understanding Nonlinear Dynamics, SpringerVerlag, 1995.
 This is an introductory text that grew out of an undergraduate biology course taught
by the authors. Thus, some of the topics covered and many of the illustrative examples
of physical experiments are slanted towards the biological sciences. This does not mean
that one needs to be a biology student to appreciate the book. In fact, I think the
biological examples cited in the text make us appreciate a little more
how nonlinear dynamics can play a major role in our lives. There is also a chapter
on timeseries analysis which might be of interest to people analyzing data.

 Lichtenberg, A. J., and
Lieberman, M. A., Regular and Chaotic Dynamics, John Wiley & Sons, 1992.
 Another classic text that is especially indepth in the treatment of Hamiltonian
dynamics. Graduate Level.
 Moon, Francis C.,
Chaotic and Fractal Dynamics, John Wiley & Sons, 1992.
 A book written by an applied scientist and engineer for (curiously
enough) applied scientists and engineers. This is one of only a
handful of books that actually deals with how an applied scientist
goes about identifying and classifying chaos in physical systems. True
to its aim, the book is filled with many illustrative examples of
chaos in various diverse physical systems including an appendix on
tabletop experiments with "chaotic toys". While it does not go
indepth into some of the topics as one would like, its breadth and
scope more than make up for it. Upper Undergraduate and beginning
Graduate Level.
 Ott, Edward,
Chaos in Dynamical Systems,
Cambridge University Press, 1993.
 An excellent text that is written in a very understandable and
careful style. It gives the readers a good grasp of the fundamentals
by emphasizing main ideas instead of harping on technical definitions.
The bibliography at the end of the book is also a good source for
readers who want to delve further into the technical literature.

 Peitgen, HeinzOtto, Jurgens, Hartmut, and Saupe, Dietmar.
Chaos and fractals : new frontiers of science, SpringerVerlag, 1992.
 The authors are the same people who gave us the nice coffeetable book
The Beauty of Fractals. This book gives a very solid and clear introduction
on two topics that has captured the imagination of the public. It has a particularly
nice discussion about the logistic map with some interesting details that I don't
think are found in other references. The computer
excercises at the end of each chapter are especially illuminating.
Undergraduate Level.
 Schuster, Heinz. G.,
Deterministic Chaos, 2nd ed., VHC Publishers, 1988.
 This book is geared towards the physics audience. While it does cover
a wide range of topics, it has tendency to be a little too
concise. This makes some of the arguments difficult to follow.
Graduate Level.
 Strogatz, Steven H.,
Nonlinear dynamics and Chaos, AddisonWesley, 1994.
 A very good undergraduate text that does a nice job of explaining all
the relevant concepts and ideas in the qualitative theory of Ordinary
Differential Equations (ODE) like bifurcations and phase plane
analysis. In addition, the book is peppered with many interesting
applications and models. Check out the amorous ODE model (pg. 138) on
how the romance between Romeo and Juliet changes as one varies several
"love" parameters. Undergraduate Level.
 Tsonis, A. A.,
Chaos: from Theory to Applications, Plenum Press, 1992. Reviewed by Dimitris Kugiumtzis.
 It gets pretty old now but at that time (and still now I believe) it was
maybe the only book focusing on the analysis of chaotic time series.
It is in fact a very simple and readable introductory book to this subject.
I use part of it as textbook in a graduate course on analysis of chaotic
time series here at the Dept of Informatics. The book begins with basic
mathematical and physical background knowledge on dynamical systems and
fractals (part I), then presents shortly main parts of the theory of
dynamical systems (part II), and then describes the methodology (up to 1992)
related to the analysis of chaotic time series, which is the main subject
(and merit) of the book (part III). Especially for this last part, most of
the work on this topic up to this date is cited or presented shortly

 A solid introduction to the mathematical aspects of dynamical systems.
Graduate Level.
 Devaney, Robert L.,
An Introduction to Chaotic Dynamical Systems, 2nd ed., AddisonWesley, 1989.
 A good introductory mathematical text at the undergraduate level. It deals with the
theory of discrete dynamical systems and include such important topics as structural stability,
homoclinic points, bifurcation theory, and the study of the Julia set. Since this is a
mathematics text, many proofs are worked out. Undergraduate Level.
 Hale, Jack, and Kocak, H.

 While it doesn't have the jazziest of titles, it is still considered one of the
classic texts in the field. You will repeatedly come back to this book to get your
mathematical facts straight! Graduate Level.

 Not an easy read by any means, but tons of useful information Graduate Level.
Numerical Considerations
 Nusse, H. E., and Yorke, J. A.,
Dynamics: Numerical Explorations, SpringerVerlag, 1994.
 A hands on approach to learning the concepts and the various aspects in computing
relevant quantities in chaos. It includes a computer disk with the program "Dynamics"
which is compatible with IBM PCs and unix workstations running Xwindows. A large
variety of chaotic systems, including maps and flows, are included in the program,
and it is fairly straightforward to incorporate additional systems into the
program (assuming you are comfortable with C). "Dynamics" provides very comprehensive
analysis tools that are always available for all the systems: Lyapunov
exponents, dimension calculations, periodic orbit finders, stable and unstable
manifolds, bifurcation diagrams, basin analysis, straddle trajectories, etc.
 Parker, Thomas S., and Chua, Leon,
Practical Numerical Algorithms for Chaotic Systems, SpringerVerlag, 1989.
 This book explains many of the concepts and techniques that are useful for
doing numerical simulations of chaotic systems. In many cases, the suggested algorithms
are presented explicitly using pseudocodes. Particularly good are the discussions about
integrating ODEs.
Collections
 Edited by Hao, BaiLin,
Chaos II, World Scientific, 1990.
 A very comprehensive set of reprints. Highly recommended for sources of
original literature.
 Edited by Cvitanovic, Predrag,
Universality in Chaos, 2nd ed., Adam Hilger, 1989.
 Another good collection of reprints. There are many articles that are common
to Hao's and Cvitanovic's books, so you need to make a choice as to which to sit
on your shelf.
 Edited by MacKay, R. S. and J. D. Meiss,
Hamiltonian Dynamical System, Adam Hilger, 1987.

This set of reprints can be considered an extension of Cvitanovic's compilations;
sort of a "Volume 2" dealing with Hamiltonian systems.
 Edited by Kim, Jong Hyun, and Stringer, John, Applied Chaos, John Wiley & Sons, 1992.
 This is a nice collection of articles about applying the ideas of chaos to real
physical systems. Topics covered range from applications in engineering and physical
sciences to physiology. There is also an appendix which is a transcript of the
discussions about many of papers in the book by the participants of the meeting.
 Edited by Ott, E., Sauer T., and
Yorke, J. A., Coping with Chaos, John Wiley & Sons, 1994.
 A more contemporary set of reprints. Very good in practical applications of chaos.
 Edited by Weigend, A., and Gershenfeld, N.A., Time Series Prediction: Forecasting the Future and Understanding the Past, AddisonWesley, 1994.
 These proceedings grew out of a "competition" to analyze various data sets that
was held at the Sante Fe Institue in 1992.
The purpose was to compare and contrast the various methods of time series analysis
which would hopefully lead to new understanding and insights about studying nonlinear
time series. This is an excellent collection of articles that surveys the latest
techniques in this growing field.

 These proceedings contain a broad range of papers reporting on real experimental results and applications of chaotic and other nonlinear phenomena. Examples of fields covered: electronics, condensed matter, biology, fluid dynamics, spatiotemporal systems, meteorology, communications, control systems, optics, and chemistry.
Popular Works
 Abraham, R. H., and
Shaw, C. D., Dynamics: the geometry of behavior, AddisonWesley, 1992.
 A visual mathematics book that uses no formulas and only colorful pictures to
explain concepts in nonlinear dynamics. Many of the pictures do a nice job of
clarifying the concepts in dynamical systems. However, it is probably more helpful
as a supplementary text after the reader has read one of the introductory texts
mentioned above.
 Field, Michael, and
Golubitsky, Martin, Symmetry in Chaos, Oxford University Press, 1992.
 A visually delightful book!! Not only is this book filled with eyecatching
colorful pictures, it also does a wonderful job of explaining how they were
generated. They also draw many interesting parallels between the computergenerated
pictures and the structures that occur in nature or are manmade. Check out the
Symmetric Chaos site!

Gleick, James, Chaos : Making a New Science,
Viking, 1987.
 A book that catapulted Chaos into the public's eyes. Written by a journalist, thus it tends to be a little melodramatic, but it does give a flavor of the nature of chaos.
It also gives interesting sketches of many of the key personalities in the development of chaos.
Especially interesting and relevant is the part where it describes how
James Yorke
"had discovered Lorenz and given the science of chaos its name" (pg. 65).
 Lorenz, Edward N,
The Essence of Chaos,
University of Washington Press, 1993.
 This book grew out of a set of lectures that Lorenz gave to a general audience
at the University of Washington, so the math is kept to a minimal (actually, no formulas
appear until Appendix 2). It's always nice to look at the science of chaos
from the perspective of one of the pioneers in the field. Also included is the text
of a talk that he gave in Washington, D.C. in 1972 which gave rise to the popular
term, "the Butterfly Effect".
 Stewart, Ian,
Does God Play Dice? The Mathematics of Chaos, B. Blackwell, 1989.
 Another popular science book that tries to give the public a flavor of chaos.
This one assumes a more mathematically literate lay reader.
Specialized Areas
 Haake,
Fritz, Quantum signatures of chaos, SpringerVerlag, 1991. Reviewed by A. OrtizTapia.
 How does the transition occur from quantum
mechanical properties to classical properties showing deterministic
chaos? ``Quantum signatures of Chaos'' includes quantum aspects of
nonlinear dynamics, antiunitary symmetries (generalized time reversal)
and the quantum mechanics of dissipative systems. There is a set of
problems at the end of each chapter. Quantum observables can display
effectively irreversible behaviour when they are coupled to an
appropiate environmental system containing many degrees of
freedom. Even in closed quantum systems with relatively few degrees of
freedom, behaviour resembling damping is possible, provided the system
displays chaotic motion in the classical limit.
