Mind boggling.......2004-06-23
Judge MacLaren Yarborough is a captivating character that makes you want to read all the books in the series over again and again! The story moves along at a tremendous speed(unlike other books I have read.) The book entices you to want to do your own sleuthing. I think that anyone who wants a book they can cuddle up with on the couch should read this book and the rest in the series.
Not A Real Mystery.......2004-01-27
A disappointment. Don't waste your time or money. More of a presentation of a sad social problem than a mystery.
MacLaren is the best!!.......2003-12-15
I have read all of Patricia Sprinkle's MacLaren mysteries and this one hit a home run. She grabbed my attention on the first page and held it to the end. I cannot wait until another adventure in Hopemore, Ga. hits the bookstore. What a great way to spend a rainy day.
The best MacLaren tale yet!.......2003-11-26
As I have read each of the books in this series, it's been a huge pleasure to get to know MacLaren Yarbrough. Ms Sprinkle does a wonderful job of developing character and story at the same time in books that are marvelously light reading. I can hardly wait for the next tale of Mac's adventures! She's definitely become my favorite accidental detective.

Customer Reviews:
Not specific to those over 50.......2007-08-19
This book is a good guide to beginning strength training for anyone. The book contains dozens of basic descriptions of machine and free weight exercises, listing muscle groups worked. However, I give this book only 2 stars because except for the title and a few charts, the book has little specific information for over 50 exercisers. Those looking for ways to tailor exercise routines for arthritis, or trying to decide which exercises stress joints the least will need to look elsewhere.
Review of Strength Training Past 50.......2007-07-13
The book is exactly what I wanted. The instructions are very detailed with pictures. One can read, and then implement the exercise personally.
Okay.......2007-06-14
Not at all what I expected. I was hoping for more things that we could use at home, rather than having to go to a gymn to use equipment there.
Nothing out of the ordinary.......2007-05-07
I was looking for different strength training ideas for my older clients but this book didn't show me anything that I didn't already know. Very basic exercises. I needed new ideas for clients that don't move so easily and have a hard time navigating a bench/ball and the floor.
Not perfect but the best around.......2006-11-28
This book should be titled "The Almost Complete Guide to Weight Training for Those over 40."
Improvements To Make it Complete
I would jettison the discussion of buying ones' own machines--that is not something for a beginner to even consider. I would drop the discussion of barbells, not worth the extra risk for tiny extra gain. I would put in a basic stretching routine and more detailed discussion of cool down and warm up. There should be more caveats about limitations on using excercises. For example, those with knee problems should not do leg extensions (ask a PT)-a doc will tell you not to hurt yourself and may send you for a excercise stress test but they will not know about detailed excercise. While the arguments are sound for doing strength training they will not convince anyone who is not primed to go.
Strengths
The organization is quite good as excercises are grouped by muscles so one can mix up their routine with free weights and machines. All the good training principle are there and are emphasized. A chapter on nutririon is essential for any exercise book for any group over 40 and they have one, although now made obsolete by the new pyramid. This is a blueprint that a somewhat experienced non-strength excerciser can use to get into weight training and go to a good maintenence level program in a few months.
This book ignores the best advice of all, go take a course in Strength and Conditioning at your local community college or Community Rec Center. But that takes time and with a few safety caveats this book is the blueprint that other books claim to be for a younger group of folks.
I will be suggesting this book to my friends who are starting or adding strength training to their excercise program.
It really has no competition for what it does it is so close to great I would like to give it 4.5 stars.
Book Description
In this delightfully surprising history, Laura Shapiroauthor of the classic Perfection Saladrecounts the prepackaged dreams that bombarded American kitchens during the fifties. Faced with convincing homemakers that foxhole food could make it in the dining room, the food industry put forth the marketing notion that cooking was hard; opening cans, on the other hand, wasn't. But women weren't so easily convinced by the canned and plastic-wrapped concoctions and a battle for both the kitchen and the true definition of homemaker ensued. Beautifully written and full of wry observation, this is a fun, illuminating, and definitely easy-to-digest look back at a crossroads in American cooking.
Customer Reviews:
Fascinating.......2006-12-23
I savored this book, and didn't want it to end. I thought the subtitle did the book a bit of a disservice: "Reinventing Dinner in 1950s America," making it sound too narrow. It is really more of a social history of the rise and fall of the housewife stereotype, seen through the lens of food, the rise of the food industry, and high and low cooking. As some of the other reviewers have stated, a few of the biographies may have gone on a bit long, but I didn't mind as Shapiro managed to make them all fascinating. In a way I really related to Poppy Cannon, an icon who I'd never heard of before and her penchant for both great food and convenience. Isn't that actually the way most home cooks make dinner these days, even those who care about tasty, healthy food? We may not be making gross jello salads any longer, but we think nothing of opening a jar of good satay sauce to flavor our Thai stir-fries.
This is the kind of book I will keep on my shelf to refer to, and to re-read in the future. I absolutely loved it!
Fascinating, fun, and a pleasure to read .......2005-07-15
There isn't much more to add to the other reviewers, but I did want to say that I picked up this book fearing it would be a bit too "academic," but the author did a great job presenting the history and research in a way that was a true pleasure to read. She made me think about issues like women in the workforce, the importance of the kitchen as the center of the home, the creative way cooks have always found shortcuts, and the like. Lots of fun stuff you wouldn't believe, too -- like all the ways to cook with Jell-O. Thumbs up.
From Betty Crocker to Betty Friedan.......2005-06-06
Something From the Oven covers almost everything about American food culture during the post-World War II years until the mid 1960s. There are accounts of the advent of convenience foods, the literature of food, the rise of cooking shows on TV, and the phenomenon of cooking contests such as the Pillsbury Bake-Off.
The topics seem loosely connected, with no particular conclusions drawn. But it's a pop history book, not an academic tome, so sit back and enjoy an entertaining look at food from several historical angles.
Shapiro talks about the post-war need for convenience food. At least, manufacturers wanted there to be a need for convenience foods, whether American cooks agreed or not. There were a lot of experiments in the first days. Successful products included concentrated frozen orange juice and fish sticks. Unsuccessful product proposals included canned deep-fried hamburgers and concentrated distilled water. (I suspect if Shapiro is having us on with that last idea.)
The section on domestic literature was especially fun, although a lot of it had little to do with food. Shapiro discusses Shirley Jackson, Erma Bombeck, Peg Bracken, Bette MacDonald, Jean Kerr, and the Gilbreths of Cheaper By the Dozen fame, among others. She reveals that there was often a big difference between their supposedly non-fiction works and their actual lives. I look forward to rereading these old favorites with this new information in mind, as well as looking up some authors Shapiro mentions that I was not aware of.
The mini-history of Julia Child's career is entertaining, and the extensive bibliography is a treasure trove of further reading ideas. Recommended!
Too much political agenda.......2004-11-13
When Shapiro sticks to the subject matter of the title of the book, she shines, as she did in Perfection Salad. That part of the book is interesting, witty and well researched. However, she loses focus often, wandering into race relations, NAACP politics and feminism. While these are admirable topics that need to be addressed, their inclusion in this book seems like filler to plump up the page count. It's forced. Shapiro seems to devote as much space to Betty Friedan as to Julia Child. If you want to read about the 1950's in general, seek out David Halberstam's eponymous book.
This book was a disappointment after Perfection Salad.
A Revelation.......2004-10-22
Conventional wisdom about the 1950s is that it was the decade in which everything went bad, and the fear of non-conformity and Communism made everything about American life bland, nowhere more so than in the kitchen, where white bread and TV dinners took over and banned fresh food and gourmet cooking from fashion. Laura Shapiro's new book SOMETHING FROM THE OVEN argues convincingly that this generalization has been absurdly overstated and that none of it is true in the least.
Her previous book PERFECTION SALAD was good-the rise of "white foods" at the turn of the century, the moment when cook books started specifying amounts in their recipes as "science," or an absurd version of it, became desirable in the kitchen.
But SOMETHING improves on PERFECTION, as it were. Shapiro plunges right in with the invention and promulgation of frozen foods, showing how American housewives took to them slowly and with the utmost discrimination, rejecting the ones that didn't taste good. She shows how serious chefs like James Beard and Dione Lucas started out scorning convenience foods but they, too eventually came to approve of some of them, using the same intuitive responses as the mass of US housewives. She then opens up the story by writing a gimlet eyed account of the original Pillsbury Bake-Off, showing how marketing and drive made the Bake-Off a double-edges sword, by promoting Pillsbury's convenience food but also showcasing the creativity and ingenuity of US home cooks.
Shapiro also reminds us that the 1950s was the age in which Alice B. Toklas published her famous cookbook. A sequel was prepared with the collaboration of the food writer Poppy Cannon, although it didn't do too well. Poppy Cannon, one of the enigmatic personalities of the food world, is given the big biographical treatment. Married to Walter White, the light-skinned head of the NAACP, Poppy Cannon led her own kind of double life for many years, and Shapiro really digs in and devours every nuance. Shapiro is also good at discussing the family comedy writers of the 1950s, who balanced home-making with feminism, including often ignored writers like Jean Kerr, Ernestine Gilbreth Carey, Peg Bracken, and the one and only Shirley Jackson. By viewing these women as integral to the story of food and food writing in the 1950s, Shapiro does us all a huge service. It is definitely one of the most intriguing and revisionary books I've read in a long time.
Customer Reviews:
To the reader in British Columbia.......2001-01-17
Bearded Dragons RETAIN SPERM. So, they almost ALWAYS multi-clutch...you CANNOT control or limit the number of clutches to 1 a year. Matter of fact, 3 is about average from a single mating session, and if housed together all year, female beardies can have up to 7 or even 9 clutches. (Best to house the male seperately to control the breeding to the extent possible.) I suggest you re-read the book, and if it doesn't have this information, that you throw it out and get The General Care and Maintenance of Bearded Dragons by Vosjoli and Mailloux.
great.......1999-09-08
I thought it had lots of info just not everything i neede
lots of very sound advice, wonderful section on behaviors !.......1998-10-15
There is a lot of great advice in this book as well as great photos an format. The sections on breeding and behavior are especially good. Being an owner of a Bearded Dragon I found the information acurate and consice. I was however a little concerned to read in the section on breeding that the females could have up to three clutches a season. I felt that tis should be controlled to one clutch per year NO MORE!! Pregnancy takes a lot out of even the healthiest dragons.

Don't bother.......2006-03-18
This guide is very incomplete! It only has the basic figures and uniforms only up to the 1990's even though it just came out in print in 2006.
COMPACT, CARRY ALONG BOOK.......2006-02-01
The Warman's G.I. Joe Field Guide is not a comprehensive, all-encompassing guide to G.I. Joe figures. Writer Karen O' Brien makes this clear in the introduction. Rather, this small (5" by 4") book serves as a convenient, pocket guide to G.I. Joe figures and accessories and includes hundreds of clear, vibrant photographs. It's the kind of book you can pack along easily when you travel to garage sales, flea markets, or collectibles shows. While it may not be exhaustive, there is still a lot packed into its 512 pages. O' Brien provides a brief history of the figure line and the opening section of photos display the various copyright marks and facial and uniform variations on the early figures.
Some figures are show loose while others are show still in their original boxes. For pricing purposes, only a MIP price is given. Another plus is that O'Brien provides the Hasbro item number for the figure (although not accessory sets). Some of the rarest Joe figures are pictured including the Soldiers of the World sets, the rare Canadian Mountie Sears figure, and the Action Girl G.I. Nurse, valued at $4000, perhaps the rarest figure of all. The various adventure sets were always my favorite as a kid and the book includes photos of these great sets including the Secret of the Mummy's Tomb, White Tiger Hunt, and Fight for Survival dog sled set. You know I still have those plastic husky dogs over thirty years later!
The first 380 pages of the book are dedicated to the original G.I. Joe line while the last 130 pages are given over to the 3 ½" line. Only figures are pictured for the 3 ½" line, no vehicles or accessories are included. As a basic, carry along guide it serves its purpose well to provide some guidelines for pricing and identification. You can get more comprehensive guides but this fills the bill for being compact and inexpensive.

Good, but not my favorite.......2007-06-16
This is a good book if you're learning how to can, and it has some good tips and recipes in it, but its not my favorite. I bought this book, along with the Ball 400 Recipes book, and I prefer the Ball book over this one.
Everything I need with a GREAT layout........2007-01-04
This book is wonderful in that it has all the information you could possibly want and it is sectioned very well. The only thing that I would prefer is a wider range of recipes for the salsas and things, but then again it is not a cookbook so I can't fault it for that.
useful book.......2006-08-23
Good book. Has sensible, usable recipes and canning/preserving information pertaining to a variety of produce. Well written and easily understandable.
Full of Information.......2005-09-27
This book is great for the the novice. It covers soup to nuts (literally)!! After my first (successful!) attempt at canning tomato sauce and pickeling zucchini, I wanted to get more out of my garden. This year we had to take a hiatus from producing our own vegatables, but I ordered this book now, so I can be better prepared for next year. This books gives tips on types of vegatables to plant, harvesting tips, and a guide on how to best preserve each item. It has also given me plenty ideas to plan for in the next few years. My goal is build a root cellar in my basement. This book was definatly worth the money for the advice it gave me.
Great guide.......2004-08-09
I've recently expanded my preserving repertoire beyond canned tomatoes & pickles and into the worlds of pressure canning, drying, and freezing. This book is perfect for the person exploring these (and other) options for "putting up" food. Especially helpful is the early section of the book with a long list of common fruits and vegetables with a summary of the best methods of preservation. Subsequent chapters present each method in detail (with good explanations of the science behind them) and provide greater detail on how to apply them to specific foods. I've also tried (with good success) several of the recipes that appear toward the end of the book. This was an excellent purchase for my needs.

Book Description
This book is about how mythology may be purposively adapted in the service of theology. It does so at the hand of Hayagrîva, since the 14th century C.E. revered as a full form of the Supreme Lord Viṣṇu in the local Úrîvaiṣṇava tradition of South India, but originally a relatively minor pan-Indian deity.
Convincingly laying bare the complexity in respect of the pan-Indian images of Hayagrîva, it makes clear that there is no single unilinear history of this deity. It subsequently reconstructs the `Úrînivaiṣṇava History' of Hayagrîva, and brings out the selectivity involved in borrowing materials from the pan-Indian and local levels.
Amidst the incredible complexity encountered here, this study exposes, however, that the emblems and functions of different images show continuity, although a god's status may change according to the sect.

Book Description
I'm innocent... I didn't do it...It wasn't me!
It began with a brutal and senseless murder. Looking for a suspect, the police grabbed the first convenient person they spotted: a 15-year-old kid named Brent Butler. The cops figured they had it solved in record time. In just hours they had an eyewitness and the killer. Case closed. The police, prosecutors, courts, prisons and the press were all patting themselves on the back before an all-too pliant and applauding public.
Except for one thing: They all got wrong. As is proving more and more common-place in our nation, the justice system screwed up. But that was just the beginning. For Brent, his family and the rest of us, over the next year nothing -- nothing at all -- would ever be the same again.
First the subject of the Oscar-winning documentary, "Murder On A Sunday Morning," now Brent Butler speaks out in his own words. In shocking and graphic detail Brent describes his horrific ordeal from accusation to imprisonment and from trial to final exoneration. And the truth is more brutal than ever: The innocent are America's latest victims.
Customer Reviews:
A shocking and severe true story.......2004-06-07
They Said It Was Murder is the harrowing true story of Brenton Butler, a fifteen-year-old black man innocently accused of a brutal murder. When he agreed to cooperate with the police, he was falsely identified for the crime, and beaten into confessing. What followed was a nightmare of trial, imprisonment, and eventual exoneration when the truth of how the police and authorities utterly bungled the case came to light. The story that formed the basis of an Oscar-winning documentary is related in thorough detail, by the innocent accused himself. A shocking and severe true story of a travesty of justice, and a stark wake-up call to the deficiences in America's law enforcement system.
