Book Description

This is the highly-anticipated, full version of the Analysis of Book 5—analogous in format to the first guide, analyzing books 1 through 4, but covering only Harry Potter and the Order of the Phoenix. Readers can use this guide as a refresher course on how to search for clues when they read Book 6, and to answer their questions about Book 5. It offers insights into the clues, as well as speculations into the motivations of the characters and their magical world, which functions so differently from our own. The authors also go on record with their theories so that the fans can have fun debating whether they were right or wrong!

Good, but not as good.......2007-06-25

I absolutely loved Galadriel's guide to Books 1-4, and this one does have all the same imformation, but the format change does make it a muddier read. In the first guidebook she would site a passage (with page number) and then discuss it in a seperated section. Now she has combined the two without any page numbers and in more of a 'free form' style.
It's still a quality guide, just harder to get through.

Great ideas and insight!.......2006-08-26

Because I enjoyed the guide for books 1-4, I had to get this guide as well. It didn't disappoint. I enjoyed their writings, their fresh ideas, and their predictions for the next book. Though I didn't always agree with things being said, they did give me ideas on which to think about. Interestingly enough, I found that my thinking is right on target with these Harry Potter sleuths. I can hardly wait for their guide on Book 6. Maybe it will be out before Book 7 is finally released.

Intriguing Hints and Questions about Order of the Phoenix.......2006-03-10

This is Galadriel Waters and friends' take on the FIFTH book--not the most recent entry--in the Harry Potter series. Unlike the first volume, which analyzed the first four books by raising questions and then answering them, this one provides few answers--but plenty of provocative questions. There are frequent references to another JK Rowling book, Fantastic Beasts and Where to Find Them, and I suggest you have it with you as you read.

Each chapter is analyzed in light of things that have happened earlier (in the first four books as well as this one). Wordplay is one of the main "clues" Waters investigates; she's certainly found puns and anagrams that I had overlooked, although I think at times she may be seeing word clues that aren't really there. Nonetheless, she has obviously put a great deal of hard work into this area of the book. She also has some interesting hints on what may have been going on at 12 Grimmauld Place that the characters overlooked.

The last section, Book 6 and Beyond, was the most interesting to me. Here are analyses about the strategic positions at the end of Order of the Phoenix, discussions of possible character participation in the next book, Half-Blood Prince, as well as of the prophecy and Frequently Asked Questions.

A Fun and Makes-You-Think Read.......2005-09-16

I am a fan of Ms. Water's books. My title "A fun and makes-you-think read" says exactly how I feel about her books, including this latest one. It is researched speculation. The idea is the speculations makes you think and come up with your own theories which may agree or disagree with the ideas presented in the book.
She comes up with ideas which would never even have occurred to me. That is what makes it fun. If you are a Harry Potter fan (even if you are over the recommended age of 9-12) this is a book for you. We need these books to get through the long waits between JKR's books and this latest one will occupy a lot of wait time. Thanks Ms. Waters

Book Description

Harry Potter's fans are down to waiting for the final volume in JK Rowling's epic mystery, and the fans at Wizarding World Press are no exception! We all want to know how it turns out, and if clues to the final solution have been sitting under all our noses in Book 6. Is Harry one of the people Rowling said would die? And if not—what else can happen to the boy wizard who's already lost his parents, his long-lost godfather, and his mentor? This is the Analysis of Book 6. It is basically the same as the first two guides but covering only Harry Potter and the Half-Blood Prince. The format is similar to the Analysis of Book 5. Many readers use these guides to help them try to guess how the series might end. They can use this one to refresh their memories of what has happened so far, as they reread Book 6. The guides look not only at the clues, but offer insights into both the motivations of the characters and the ways of the magical world, which functions differently than our own.

A Great Read for HP Fans..........2007-09-22

For those who are TRUE HP fans, this book is a great read. It's good to go through, even if you've already read "Deathly Hollows". There are still some unanswered questions and issues that this book covered, AND it has a lot of information here on all kinds of things - like the tarot imagery (hanged man, lightning-struck tower, etc.) in "Half-Blood Prince" and the other novels. Also, if you were a fan of the late great Madeleine L'Engle, you'll be floored by the ties between "Wrinkle in Time" and the Harry series these guys spotted. They even predicted that there would probably be somebody important kidnapped to force Harry's hand, just like in "Wrinkle", and of course there was.

Also, there were lots of fun finds, too. If, like me, you ever wondered how a kneazle might communicate... well, you need to read this book. They even spotted something that I completely missed. There's just tons of stuff! It gets kind of wild sometimes, but that's part of the fun.

I really like this guide series, it goes right along with the books and lets you think more about everything, it's almost like getting extra Harry books!

Unfortunately, this book got out just before "Deathly Hallows", which was a little bit of a disappointment, because I was really looking forward to having time to go through it all before "Hallows". But the research that went into it is just as amazing as the rest of their series. Like the previous guides, it has lots of definitions and backgrounds for words, plus other goodies that helped me appreciate Ms. Rowling's work even more.

The only suggestion I might make for any possible future editions is the addition of an alphabetical appendix, in order to find specific references in the analysis itself, to various characters, places, etc. There is so much in here, it's hard to sort through it all if you have a specific character or place you want to research.

Bleh. Not spectacular........2007-09-07

I also have read all the other guides, and was really looking forward to this one. I don't know if it was Amazon, or the publisher, but the book came out a few weeks AFTER the 7th book. So there are tons of parts where I just skip over it. The details were starting to get very tedious. For example, they mention the part where Dumbledore is walking into the orphanage to see Tom Riddle for the first time. They note that the hallway has black and white tiles. Then they go off talking about chess, and pulling clues out of it. Now maybe because I already read the last book, I know that the orphanage just happened to have black and white tiles, and it is meaningless.
Like the previous reviewer said, they do not explain other parts enough. In fact, in one chapter, you are told that the answer to this particular clue is in the restricted section. No, actually, it is not. I have no idea what they are leading too, and there is no way to figure it out.
I just wish they would have spent less time picking apart every teeny, tiny thing, and concentrate on the bigger picture. It would have been so much better to read this book before the last book came out.

a bit of a disappointment.......2007-08-18

Err. It's ok.
Typos abound & drive me crazy. Shouldn't true HP fans know how to spell "Ollivander"? Not to mention the countless other grammatical mistakes and "regular" English-language words misspelled.
I've read all their other guides, so was prepared for the casual, web-style grammar and word usage. But, after reading the other guides, I was still expecting some really thoughtful, deep insights into the book, and have so far been disappointed. Most of the time, they start leading the reader in a general direction and then leave us hanging, saying they want us to be able to "figure it out" for ourselves. But most of the time, that seems impossible. I have no idea what they're getting at & I've read & re-read all the HP books at least 10 times (Deathly Hallows three times). The authors touch on all sorts of theories, but just do a really poor job of expounding on them. I wish they would have chosen just a few interesting possible theories and gone all the way with them.
A big disappointment.

WRONG EDITION!!!!.......2006-04-25

The page says the 9th Edition, which was written in 2001, for sale. Used and new starting @ $29.41. The catch is, all of the used books are earlier editions. Most are from the sixties. When I ordered the book, I expected to get the 9th edition. I received the 6th edition. What a joke. This is a total misrepresentation of the price. Amazon should be ashamed of this type of shady business tactic. Now I have to spend ~ $200 to get a new "9th" edition. Amazon should not have earlier editions on the same page. This is nothing more than 'bait and switch' tactics. Shame on you Amazon.

I received a book from 1961, the 6th edition. The order was for 9th edition

The book is informative. The practices by Betz are bad........1998-12-29

This book was written and published by a marketing company. The expertise of the Betz employees is poor.

Considered a mandatory guide for good boiler water treatment.......1998-10-31

This book covers the basics of water treatment from the beginning of use to the end. It covers water constituents, impurities, clarification, ionization, etc. It also covers hot and cold use and treatment. Biological waste treatment and methods of treatment are also covered. The book gives fairly well detailed test procedures for boiler water samples and for cooling water samples. This is one of the best books available on the market for basic water treatment in a small setting.

Book Description

The Ultimate Unofficial Guide to the Mysteries of Harry Potter: Books 1-4 shows would-be sleuths how to hunt for JK Rowling's clues in a fun-to-read manner. With this Guide in one hand and the Harry Potter books in the other, you'll read the series in a whole new light as you:

• uncover the detail with which Rowling has crafted her story and her world • delve below the surface to ferret out Rowling's sly clues

Not only will you be amazed at how deceptively Rowling's hidden those clues, you'll learn how to discover new ones on your own! There are questions in Books 1-4 Rowling still hasn't answered, even after Book 6! Do you know what they are?

The Ultimate Unofficial Guide to the Mysteries of Harry Potter is for you if:

• You're new to the series and want a leg up or • You've read all the books, but it's been a while.

Pull out your memories for another look and tighten your skills!

Do you know how to solve Snape's poison bottle puzzle in the room "through the trapdoor?" Did you know there are actually 2 solutions to that puzzle?

Do you know what Rowling told us in the first four books about the secrets Neville and Professor Snape hold? Do you understand exactly how Dumbledore's "Mirror of Erised" worked? (Rowling's said we'll see it again!) Are you aware that what Harry saw in the Mirror was not accurate?

Here's what the Guide says about spotting a clue: "In chapter 16 of Book 1, J.K. Rowling writes that Harry 'watched an owl flutter toward the school across the bright blue sky, a note clamped in its mouth.' Even after reading the book several times, it still catches readers by surprise when they realize that this note was the message used to trick Headmaster Dumbledore into leaving the school for a trip to London. That clue doesn't help us solve the plot of the book and it was never explained or mentioned again, but when we then see a similar clue in Book 4, we need to pay much closer attention! Look for yourself - it's awesome!"

The Ultimate Unofficial Guide to the Mysteries of Harry Potter is best read alongside JK Rowling's books—not as a replacement! It does not give the plot away in advance, but there IS a spoiler warning because it discusses the endings of each of the books in chronological order.

No Harry Potter collection is complete without the Guide. Written by fans for fans, it is the perfect holiday gift for the Potter fan in your life—or yourself!

Customer Reviews:

Oh, the joys of analyzing!.......2007-01-10

Here's a great little book that carefully and fanatically considers every scrap of information in the first four Harry Potter books. It is made for the hard-core, obsessive fan, and I'm sure that they will love it. It's charmingly written as it analyzes information in a delightfully hard-core way. I originally purchased it back in the day, and even now I have a great time going back through it. Some of the ideas are admittedly funky, but the whole book opens us a fun new approach to the wild world of Potterholic fandom.

Very Interesting read.......2006-08-26

I enjoyed this book very much. It gave great insight as to the meanings behind the writings of JK Rowling, and much to think about as far as the books go. Anybody who loves the Harry Potter books will enjoy reading this guide. Great entertainment while you wait for Book 7.

Harry Potter 1-4 Notes.......2006-08-21

I thought that I had read books 1-4 thoroughly at least twice each, but after reading this hint book I need to go back and read them again. A lot of work went into this analysis. Harry Potter fans will find this an excellent book to accompany the series.

Ultimate Unofficial Guide to the Mysteries of Harry Potter (Analysis of Books 1-4).......2006-07-10

I really liked it, it gave a lot of insight on what things may unfold in the books to come. I enjoyed the set up, everything was neatly organized, the Chapter-by-chapter analysis was pretty good, I would recommend this book to everyone, even though two more books have been released, it still is a great read.

A Must Read.......2006-04-08

Although some of the "detectors" of mysteries were silly this book gives a lot of insight into the unknown relms of Harry Potter. It makes connections I wouldn't have noticed as many times as I have read the books. It's a great book to read!

Book Description

The state of the art of the impact assessment of recycled hazardous waste materials on surface and ground waters is presented. The topics include chemodynamics, toxicology, modeling and information systems. Due to the wealth of information on this topic, the texts of T. Kassim (ed.): Environmental Impact Assessment of Recycled Wastes on Surface and Ground Waters are published in three separate volumes: vol. 1: Concepts, Methodology and Chemical Analysis; vol. 2: Risk Analysis and vol. 3: Engineering Modeling and Sustainability. The book serves as a practical conceptual guide for those who have professional responsibility for the monitoring, design, management, or conduct of environmental impact assessment. It is believed that the book will prove useful to the reader who, regardless of disciplinary background, wants to examine in greater detail the kinds of interdisciplinary contributions to contemporary decision-making processes that characterize modern impact assessment project development. Each volume contains the contents of all volumes.
