This is a wonderful book for kids of all ages. The reference works in back to museums, internet sites and other books is well done. I recommend this book for any one who has children interested in Knights and Castles!

I'm an artist and art teacher, and after discovering this book, I ordered copies for my middle school ART students! While it's an easy read for students of this age (5th through 7th grade), it's packed with understandable text and pictures. It's a great reference for the various art projects that my students are doing as part of our study of the Middle Ages, and the kids have really enjoyed it....

Mary Pope Osborne does it again!

Our Family loves the Magic Tree House series. They hit us on many levels. Our youngest loves to be read to, our next just hit chapter books, our oldest is beyond this intro. level chapter books - but loves this series & reads the books over and over.

I am delighted to introduce reasearch ideas in such a non-threatening, inviting manner to my children. Learning and reading is so fun; and this concept sheds new light for a young audience. Not only will this help after reading the MTH series, it will add a new dimension when going on field trips, museums, the library, the internet, etc. I am going to share this book with our elementary school.

Ms. Osborne and her husband take the opportunity to be thorough, while simplifying for young minds - and the illustrations keep a young reader's attention.

Bravo! Keep 'em coming.

My 4-year-old son and I have been reading the Magic Tree House series for nearly half his life; they are among his favorite books (in fact, when given an opportunity at a book sale at day camp this summer, he opted to buy the next book in the series rather than the Pokemon cards that all his friends were buying!). When I showed him the Knights and Castles Research Guide, he was thrilled! We started reading it right away, and he found it fascinating. Especially appealing are the illustrations, much more numerous and detailed than those in the regular series. My only (very minor) disappointment is that it would have been even more wonderful if these books in this Research Guide series had been presented as if they were the actual books that Jack and Annie found in the treehouse (complete with the quotations that appear in the Tree House books), rather than ones they put together from "research" after their visits.
