With all the uncertainty and hoopla around the Internet, how can investors and business managers hit the right financial buttons? In Net Profit, Peter S. Cohan, a premier Internet consultant and stock picker, analyzes the trade's top companies--including Yahoo!, Amazon.com, America Online, and Cisco Systems--and offers some compelling insights for investors and businesses on the Web or those considering it. "This book is about the companies that are working to make economic sense of the Web," Cohan writes. "And it is about a search for the business strategies that distinguish the market leaders from their peers."

Cohan identifies nine segments of the industry--infrastructure, consulting, venture capital, security, portals, e-commerce, Web content, Internet service providers, and commerce tools. He judges each of the leading companies in the nine fields on its management, breadth of customer service, and most critical, ability to deliver a product that is so scarce and important that it carries a high price. Most Internet companies fail to meet all of Cohan's strict standards. Portal leader Yahoo!, for example, lacks economic clout over advertisers because of tough rivals in the traditional media. Cohan gives high grades to technology consultants like Gartner Group, venture capital firms, and network builder Cisco. He loves Cisco because it controls 80 percent of the router market, keeps customers by providing other network components, and shows a knack for acquiring smaller companies. Easy to understand, Net Profit features some key strategies for competing on the Internet. Cohan also helps companies evaluate whether it makes sense even to offer services on the Web. --Dan Ring

Book Description

The recent Internet stock crash has caused investors and managers to throw the baby out with the bath water. The gloom surrounding many publicly traded Internet companies makes objective evaluation of their performance difficult. In Net Profit, author Peter Cohan breaks down the complexity of the Internet market by answering two basic questions: Who makes money on Internet-related business? And how do they do it? His incisive analyses of leading Internet companies, their competitors, and their chances for continued growth pinpoint the factors that investors and managers in Internet business must examine to ensure future success.

5 out of 5 stars Highly Recommended!.......2001-08-14

At the peak of the dot-com bubble, buying Internet stocks was momentum investing at its most pure - get in when a new stock or sector is on its upswing, and get out while the gettin's good. But Peter S. Cohan has created new criteria for Internet investors to apply in the traditional method of fundamental analysis. Instead of looking to old-line gurus like Graham or Buffet for advice, Cohan draws on the business strategies of John D. Rockefeller to come up with fresh e-commerce attributes like economic leverage, closed-loop solutions and adaptive management for investors to measure. We [...] recommend this book to executives, employees and students with equal vigor, although consider yourself forewarned that Cohan's extended barking-dog analogy will grate on your nerves. Nevertheless, anyone who invests in Internet companies or even traffics in Internet commerce for business or pleasure will gain insights from this book, regardless of whether Cohan's investment criteria prove to have staying power.

Practical and effective. A balanced book with an understandable writing and depth of analysis.

3 out of 5 stars Entry level.......2000-05-28

This book is good for Newbie to the internet but certainly don't worth a look for someone looking for insight.

The framework is nothing new but more or less a simplified business plan.

In Chapter 13, Advice for Internet Management and Investors sounds like a common sense and existing strategy using by most of the dotcom. Common Sense: Strategy 1 of those advices is moving the company into a more profitability region in short. (It dividies the market into 3 levels of profitability. so called Lossware, Brandware and Powerware. Well, no matter if it is New or Old economy, there is always different degrees of profitability.)

Existing strategies: Selling out of a porfolio builder, deep pockets and restructuring. We are seeing consolidation in the market a long long time ago and a lot of big or small players already know it is the way.

This book is more like a news reporting and a lot of newly invented words cannot make this book a standard of new economy rules but disappoint me only.

5 out of 5 stars Net Profit.......1999-12-14

This is the most lucid, sensible analysis I've read thus far of the likely implications of engaging in e-commerce from different strategic perspectives and business models. Cohan provides a valuable framework and applies it to scores of real cases. I find myself returning to his book time and again to apply his methodology. His only off-base advice: don't invest in companies led by folks over 35. I'll forgive him that one. The rest of the book is a real gem. It should age well.

I enjoyed the book tremendously, and think Peter's done a fabulous job dissecting the Internet investment frenzy, providing the logic to the momentum everyone else seems to have missed.

Product Description

Based upon 17 years of ongoing research involving more than 40,000 people from over 25 cultures, extensively field-tested, and adopted internationally by Fortune 500 companies, Human Dynamics? is a developmental system that demystifies the complexities of how people function and interact with one another. Human Dynamics presents a powerful framework for understanding the distinct ways in which we process information, learn, communicate, relate with one another, manifest stress, maintain well-being, and develop as human beings. At the heart of Human Dynamics are the three universal principles we all share in different capacities--mental, emotional, and physical--fundamental threads that cross culture, age, race, and gender to unify us all. As we learn to appreciate our commonalities and differences, we can use our unique gifts and apply new understanding to enrich our relationships, heighten "collective intelligence", communicate more effectively, work together more productively, enhance creativity, optimize team learning, and strengthen organizational performance. Actual accounts from major companies including Intel Corporation, Intermountain Healthcare System, and London Life Insurance Company document how Human Dynamics can optimize business relationships, organizational learning, teamwork, and communication.

5 out of 5 stars A Proper Examination and Explanation of Human Action.......2001-01-24

If you have found most personality tests insignificant, unhelpful, or unrevealing, then perhaps this book is for you. Human Dynamics goes into much more depth and provides a greater understanding of human communication and actions than any simple personality test. While people can be placed into certain "dynamics," these dynamics are not nearly as restraining or stereotypical as personality tests tend to be. Rather than explaining one's personality, dynamics explain how groups of people tend to process information, not necessarily how aggressive, passive, or "likeable" they are. This book helped me in terms of personal discovery, and has also helped me understand why it always seemed that so many people "just never seemed to think like me."

5 out of 5 stars Great book.......2000-07-09

Models to describe human personality are presented. Each model has it unique characteristics, its strengths and weaknesses. Each model will respond most effectively to certain modes of communications. This understanding of the different models presented will help a manager, a teacher, a student or just about anybody to understand themselves and people around them better. This will enable better communication of ideas and thoughts. Students will learn better and managers will be able to communicate more effectively with individuals. The models can be taken up to an organizational level. The applications of this book are far and wide. It is also simply and clearly written.

5 out of 5 stars improving teamwork in your organisation,family & community.......1998-11-06

the first time that I have found an approach which looks at humans holistically and systemically. It is not a group of personality characteristics describing superficial behaviours, but a way of understanding and recognising internal processes particular to various human dynamics. It therefore goes much deeper than any other personality assessment technique I have seen and because of this can not be reduced to a paper and pencil test. However, the gift this approach brings is that it can be taught to everyday people and can provide access to better relationships and a greater understanding of how to release our judgement of others. A truly life changing book.

5 out of 5 stars A most complete study of human diversity........1998-08-24

It is obvious that Dr. Seagal has worked extremely hard to confirm her research since 1979. Her style of writing is clear, concise and void of jargon. I found the content easy to absorb, understand and apply. Just the heightend awarness of how diverse we are has made a significant difference in how I work and related to people. I can see some real possibilities for applying in a business context.

    Book Description

    Have you ever wondered what happened before the Big Bang, or how we would colonize Mars, or what an alien invasion might really be like? Astronomer Bob Berman has, and in Cosmic Adventure, a collection of twenty-six profound to outrageous essays, he takes readers on a mind-bending tour of the universe, including our own planet Earth. From the most extraordinary cosmic phenomena to the basics of the natural world, Berman challenges us to look at the facts, discoveries, concepts, and awesome wonders of our cosmos in a new light. Written in entertaining, jargon-free language that even a novice stargazer will understand, Cosmic Adventure is a fun-filled, thought-provoking exploration of the secrets beyond the night sky.

    Bob Berman takes you on a stellar journey in this collection of twenty-five essays that display a lively mix of science, astounding facts, personal anecdotes, and sheer playfulness. Complex, mind-stretching scientific topics become understandable in human terms as Berman links astronomy to our lives. He explores strange new mysteries raised by recent discoveries, and covers areas that haven't been discussed anywhere else before. From the "night terrors" that have haunted humankind since time immemorial to the penniless eccentric who sleeps inside the revolutionary telescope he designed, Berman's scope ranges far and wide.

    Cosmic Adventure explains aspects of the physical world that have often piqued our curiosity. Who gets to name the stars? What would an alien invasion really be like? What's the inside story behind space program disasters? Why was the early Hubble goof avoidable? What's the only original idea in recent science? Why does time probably not exist at all?

    5 out of 5 stars So-So Writer.......2002-05-09

    I loved his first book (and I think I loved this one) but Berman's writing style often got in the way of this one... His attempts at humor and flowery writing just got out of hand here... Read the book, it's otherwise quite good, and see if you don't agree.

    5 out of 5 stars Great Writer.......2000-05-05

    With this book, Bob Berman proves once again what an exquisite writer he is. He is funny, concise and profound. Bob has the extraordinary ability to make even the most difficult concepts in astronomy easy to understand and fun,too! His talent is drawing the layperson (such as myself) into this amazing universe and showing how humans while understanding the most difficult concepts are able to apply them to everyday life. His love of science, life and his hilarious sense of humor are apparent from beginning to end. I strongly recommend this book and his other one "Secrets of the Night Sky". Bravo.

        What does matter look like at the molecular and atomic level? Why are leaves green? Why do colored fabrics fade upon repeated exposure to sunlight? Why does a pencil leave a mark when dragged across a sheet of paper? All of these basic questions have molecular answers that teach and illustrate chemical principles. Nivaldo Tro introduces each concept with a thought experiment, then develops the chemical principles and concepts involved in a molecular understanding of the experiment. Once students have grasped the basic concepts, they are introduced to consumer applications and environmental problems related to the concepts. Mathematical aspects of chemistry are optional.

          From the opening example to the closing chapter, the Second Edition Update of CHEMISTRY IN FOCUS maintains a consistent focus on explaining the connections between the macroscopic world (what we can see) and the molecular world (what we cannot see). With multi-part images that feature photographs of everyday objects or processes and magnifications that reveal the molecules and the atoms responsible, the book's "molecular vision" art program is truly unique. In addition, Tro develops students' appreciation for the fundamental role the molecular world plays in our daily lives and an understanding of how major scientific and technological issues affect our society. With coverage of global warming, ozone depletion, acid rain, drugs, consumer products, and even the infant field of nanotechnology, the book is always contemporary, always fascinating. This Update includes CNN Videos free with every new copy of the text and is now paperbound at the same low price.

              Book Description

              This is a book about the dramatic periods in the Earth's history called mass extinctions - short periods (by geological standards) when life nearly died out on Earth. The most famous is the mass extinction that happened about 65 million years ago, and that caused the death of the dinosaurs. But that was not the worst mass extinction: that honour goes to the extinction at the end of the Permian Period, about 250 million years ago, when over 90% of life is thought to have become extinct. What caused these catastrophes? Was it the effects of a massive meteorite impact? There is evidence for such an impact about 65 million years ago. Or was it a period of massive volcanic activity? There is evidence in the rocks of huge lava flows at periods that match several of the mass extinctions. Was it something to do with climate change and sea level? Or was it a combination of some or all of these? The question has been haunting geologists for a number of years, and it forms one of the most exciting areas of research in geology today. In this book, Tony Hallam, a distinguished geologist and writer, looks at all the different theories and also what the study of mass extinctions might tell us about the future. If climate change is a key factor, we may well, as some scientists have suggested, be in a period of mass extinction of our own making.

              4 out of 5 stars Tough read but worth it.......2007-01-10

              This compact little book has more information about so-called mass extinctions than you may want to know. It's a tough read for the non-geologist/scientist and I found I had to take it in small bites. BUT, it is worth the effort. His analysis of causes, his conclusions and his final overview of current global warming are excellent. He certainly puts the end to ideas of extinctions which happened overnight and shows how a combination of factors may have been necessary to achieve the death toll of most living things.

              4 out of 5 stars The author should stick to science.......2006-10-11

              This book presents a great deal of information on mass extinctions, and it provides an excellent overview of how geologists and paleontologists gather evidence of the causes of mass extinctions. What they can garner from the geologic record is amazing. He also discusses the theories of other geologists in a very respectful manner. Dr. Hallam pokes holes in the asteroid theory for the mass extinction 65 million years ago--wiping out the dinosaurs--although he says that the asteroid may have delivered the final blow to the already dwindling species of dinosaurs.

              My only quibble is that the author includes some little anecdotes about his research trips and the local people who helped him. He notes that he doesn't want to sound patronizing, but he does--VERY patronizing to the point of being offensive.

              However, this book does an excellent job of explaining what we can learn--and what has been learned--from the geologic record.

              3 out of 5 stars Requires patience and some prior knowledge.......2006-09-21

              Hallam impresses me as a careful scientist who has assimilated an immense amount of material. I enjoyed this book, even when the detail and vocabulary were daunting. However, I don't think it was particularly well written, and if you don't already have some background in earth history, do not even think of starting with this book. The book is written in kind of a monotone, without enough focus on the key ideas, and without enough summary material (despite a previous reviewer, most chapters don't end with any summary). Figure 9.1, extinction name vs contributing causes, does provide a nice overall summary, in fact all the figures are very helpful. The subject is inherently confusing because there are relatively few conclusions on which there is consensus.

              It is probable that only the extinction involving the dinosaurs, at the end of the cretaceous, was caused by extraterrestrial impact; it is "volcanism" which is actually associated with many extinction's. Think not of a terrestrial volcano blowing its top, but sustained undersea activity which raises the seabed enough to cause worldwide inundation, and the release of sufficiently large quantities of dissolved methane to cause a greenhouse effect. Associated with volcanism is the impact of tectonic movement, with its consequences for global climate and ocean currents. Remember that for older extinction's, the benthos (organisms living on or in the sea bed, most importantly on continental shelves) was particularly important, and warming waters, as well as deeper waters, could cause a lack of dissolved oxygen. Warm water holds less oxygen, and this is aggravated by a lack of strong ocean currents which are normally driven by large temperature gradients between polar and tropic waters.

              The last chapter on extinction's caused by humans is very readable and can be read by itself. For readers interested in earth history, I recommend Nick Lane's book, "Oxygen", part I. Even though it focuses on atmospheric oxygen levels, many important concepts are explained.

              5 out of 5 stars Theory of Mass Extinctions for the Serious Beginner.......2006-08-10

              Other reviews on this page give a fair idea of the contents of this book and so, as with most of my science reviews, my main goal here is to describe the technical level so that potential readers can decide if this book is for them. (If you're interested, you can click above on "See all my reviews" for more. There are at least two pages.) This is especially urgent since one of the previous reviews (of the paperback edition) says that Hallam "keeps his use of professional terms within the reach of the basic reader..." while another reviewer (of the hard cover) says the book is more appropriate for specialists than for general readers. I have seen only the paperback and it has a LOT of jargon, words such as "Frasnian", "tectonoeustatic", "chronostratigraphy", "brachiopod", and "paraphyletic". I still say this is a book for beginners because it doesn't require much prior knowledge. All of the terms the reader will need to know are defined in the book; many are defined more than once, in case the reader has forgotten in the meantime. (That will often be the case.) One doesn't need to know mathematics, geology, chemistry, or the history of life.

              There are also a great many undefined terms but, in general, there is no need to know the definitions. They are mainly names of kinds of organisms and the point Hallam is making is that a lot of kinds of organisms went extinct at the same time. For example, it doesn't matter if you don't know how rugose corals differ from other corals; the point is that the kinds of animals that built reefs before the Permian extinction disappeared in that extinction. Some readers will be uncomfortable at first with getting the gist of an argument without understanding all the words, but I think most will get used to it.

              Hallam also has a very good chapter on the effect of mass extinctions on evolution. In particular, a pair of graphs shows a remarkable change in diversification of marine life about the time of the Permian extinction and another in land life at the time of the K-T extinction. I have always been interested in evolution, so this is the most interesting thing about mass extinctions for me. And there is a final chapter on the Holocene mass extinction, which is currently being carried out by humans.

              There are two other books on mass extinctions which I have read and reviewed and which may be of interest. One is by Hallam and his colleague Paul Wignall. It covers essentially the same ground as the current book, but it is at a more technical level and it assumes the reader knows many of the terms that are used in the current book. The specialists that another reviewer mentioned would be much better off going directly to Hallam and Wignall, as would anyone who I familiar with the 5 words I cited above. Readers who absorb much of the vocabulary in Hallam might well like to go on to Hallam and Wignall.

              The other book is by Douglas Erwin. This is more technical than Hallam but less technical than Hallam and Wignall. It also covers only one mass extinction, that of the end-Permian, and so there is less vocabulary to keep track of. The end-Permian is the most exciting for me, not only because it was more massive than the others, but even more so because one of the groups that was nearly wiped out was the the synapsids, the ancestors of mammals. One more extinction in that group and we might not be here. Erwin also has an excellent discussion of the significance of carbon isotope ratios.

              In sum, if you want to learn the science of mass extinctions and not just descriptions, if you know only a little about palaeogeology and marine palaeobiology, if you like to work at learning, and if you're not intimidated by a lot of new words, This book is an excellent place to start. Some readers will find it so complete that they won't need more.

              5 out of 5 stars Supurb overview on the topic of extinction.......2006-06-17

              Catastrophes and Lesser Calamities by Tony Hallam is a well written book on the topic of biological extinction through time . The volume is essentially a rewrite of the book he and Dr. Wignall wrote together in 1997 (Mass Extinctions and their Aftermath). While the latter is far more technical and probably more than the average person with an interest in paleontology and extinction events is willing to undertake, the present volume is written very much with the a vocational reader in mind.

              The book has a very readable style, revealing the author's erudition in its sentence style, vocabulary choices (my favorite is "depauperate" with respect to a description of the diversity of a particular fauna), and thorough knowledge of the recent pertinent literature. He keeps his use of professional terms within reach of the basic reader and provides a glossary of terms at the end of the book. While he has some "attitude" with respect to certain issues, he addresses everything in a thoroughly gentlemanly manner, giving credit to the work of others, and when he disagrees with findings makes his point graciously and with evidential support. Students writing papers would do well to study his style and approach to argument.

              The earlier book with Wignall addressed extinction as a series of specific events. It looks at each event, discussing the date, type specimens, and facies locales throughout the world that support the likely diagnosis of mass extinction and reviews the scientific data that suggests how they might have come about. The present book looks at extinction as a process that effects life and evolution through time. While specific events are discussed in an organized way, the author focuses more on the nature of proposed extinction processes. The most commonly and widely known of these causes are the bolide impact, anoxic aquatic or atmospheric conditions, volcanism, and climate change, each of which is examined in depth using specific extinction events to discuss the data.

              The section I found most interesting was "Pulling the Strands Together." This was because it reminded me of other authors I've read on other subjects, the topics of which seem to have implications for extinction as a process.

              One is Stuart Kaufmann's work on self organized criticality which discussed, among other things, a topography of fitness within a set of parameters. He introduced a diagram illustrating, through the rise of peaks from a baseline terrain, that life tends to organize itself in such a way as to make optimal use of the fitness terrain. He notes that, when conditions are altered especially when rapid, those at the peak are not able to hop from one peak to a better one. Their failure to adapt brings about extinction, and others along the lower slopes make a transition to a new peak fitness profile. As Hallam notes, catastrophes may occur too quickly for many taxa to adapt in a Darwinian manner, which leads to disappearance. However, where change is slow enough some taxa that seem to have disappeared may in fact simply have evolved into a descendant species. They sort of back down the old fitness slope and head off in a new direction.

              Another author that is brought to mind is the theorist Per Bak, who studies self organized criticality and event probability. The discussion of periodicity/episodicity of extinction in Dr. Hallam's work reminded me of Dr. Bak's discussion of earthquakes, landslides, and similar events. In this case, the author notes that the frequency of occurrence of any possible event will lie along a curve that measures the probability of a given magnitude. In this instance, extinction might be seen as ranging from extinction of a single of species to the end of all life on earth. In short, Bak believes that all events that can occur will do so, but that they have a different probability of doing so. As with the disaster in New Orleans during Hurricane Katrina, it isn't a matter of "if" but of "when" the event will occur. The events as they occur through time, however, form an irregular curve with many small peaks punctuated with the random introduction of a few very big ones. The issue for disaster planners and others is that of prediction and preparation, so an effort is made to find a "periodicity" in the data that isn't necessarily there to find. This sounds very much like Dr. Hallam's discussion of the attempts to pin down a periodicity in the data of extinction events. Humans are very good at seeing patterns in random data, but ultimately all that can be said is that "if it has happened, it can happen."

              I'd recommend the book to anyone with an interest in paleontology, paleoecology, and extinction events. It would make a lovely book for an introductory course on earth history, or in paleontology, and an excellent syllabus entry for a course in earth science for teachers.

              A wonderful book, full of information, and well written.

                  5 out of 5 stars A Must Have For Serious Sasquatchery.......2007-04-18

                  This is probably the first book I ever purchased on the subject. Not the first ever read though. Not a bad place to start a serious book collection of this topic. Reads like a well made movie. Sometimes quite humorous. Rene Dahinden was considered one of the true pioneers in the hunt. Makes me regret the missed opportunity in 1996 while vacationing in British Columbia, of not giving him a call after finding his number listed in the Vancouver area phone directory. We've lost one of the giants of the hunt.

                  4 out of 5 stars One of the "Big 4".......2005-06-08

                  During the reign of the sasquatch/bigfoot mania from the 1960s to late 70s, there were the "Big 4" names in sasquatch research - Grover Krantz, John Greene, Peter Byrne, and Rene Dahinden. This is Dahinden's book written with Don Hunter. It is obvious that Hunter wrote the book with Dahinden's input and you can see the distinctive spots where Dahinden adds his flavor to it.

                  This is a prime book for someone that is generally interested in the bigfoot phenomenon as Dahinden relates the classics, the less-than-classics, and a few minor other stories. Of the Big 4, Dahinden was probably the most in-the-field, his passion bordered on obsession and he notes in the book that it cost him his marriage. Dahinden was a no nonsense researcher and he didn't hide it. Also he points out that he doesn't necessarily believe that sasquatches exist so much as he was adament about finding out the source of the massive amounts of footprints left in the Pacific NW and British Columbia.

                  The book itself covers all the classic stories of Jacko, Beck at Ape Canyon assault, the Ostman Kidnapping, the Baumann attack, Cripplefoot tracks, and Patterson's film. Dahinden/Hunter also cover the lesser known classics of WA skier Carter's dissappearance, the Chapmans of Ruby Creek, and William Roe's close up observation of a bigfoot. He throws in a smattering of even lesser known sightings also. Dahinden also gives coverage of hoaxers Ivan Marx and Paul Freeman that always seemed to run into a sasquatch no matter where they went. He also talks about the multiple failed 'expedition hunts' and his partnership and falling out with John Greene.

                  Overall, this is a great book for the mildly interested bigfoot fan as it covers all the stories. For the avid follower, this book is a must even though it is dated to 1980s. You'll get the classics and more from one of the vital members of early sasquatch investigation.

                  5 out of 5 stars An excellent book about bigfoot and the bigfoot hunter........2003-10-12

                  This is a very good book about Rene Dahinden who has since past away. Rene was the ultimate bigfoot hunter but one who should be respected because even though Rene spent most of his adult life in search of the creature he never found it. In fact Rene never claimed that bigfoot was real or that it existed at all. He was just interested in learning what he could.

                  Rene came to Canada from Switzerland in the 50's. He was one of the organizers behind the Harrison Hot Springs B.C. Centennial celebrations in which he started a monster hunter competition for the elusive creature.

                  It is a remarkable story about someone who turned up lots of new things sasquatch related but never once saw a bigfoot himself. His story revolves around his work with John Green and his failling out with the same man. Rene is one of the first sasquatch hunters to investigate the Bluff Creek footprints and was responsible for the release of the famous Patterson bigfoot film. He also worked closely with Russian bigfoot researchers and brought many of their findings to the west. This was an extremely important development in bigfoot research.

                  This is a very good book about Rene and his hunt for the sasquatch with lots of chapters that relate to the above. It is pretty much told in a way that doesn't try to push the idea that Sasquatch is real! and you will learn a lot about the history of sasquatch and how it all began right here within these pages.

                  This book is an excellent start to anyone who wants a good take on the whole bigfoot saga.

                  3 out of 5 stars Investigator Rene Dahinden's search for the Sasquatch.......2000-04-28

                  This volume was originally published in the early 1970's and has been updated in the 1990's. Mr. Dahinden has been a long time searcher for the Sasquatch. The sighting reports are detailed and have been investigated by Mr Dahinden. Unfortunately, a large portion of this book is spent telling the life story of Mr Dahinden and his difficulties with other Sasquatch Hunters which is really irrelevant to the subject at hand. However when the book does not stray from the subject it is quite interesting and presents strong evidence for the existence of this animal. This book is a must for all readers interested in this subject. Of a note of interest, Mr Dahinden is the one who owns the copyright on the 1967 Roger Patterson film. Since he knew all of the people involved in the film, it would be great if he would one day write a book on the history of the film and the events leading up to the filming and afterwards.

                  3 out of 5 stars It is good, but, dated.......1999-04-27

                  The book is interesting in its' historical perspective. However, Dahinden's work is dated and he has not contributed much to the field in years. I would agree that every book shelf needs a copy, though.
