Finally also check out some of the sites below for more information. From Dinosauria Online . This site is an excellent dinosaur information resource for families with younger readers. Dinosauria Online which I also mirror on behalf of its author Jeff Poling is another of my two favorite sites. Several of the museum web pages have lots of good online information about dinosaurs in general.
Books are still a more important resource and the best one for dinosaur information.
I recommend the following books, especially the first three. This book is a good encyclopedia of information, current ideas on dinosaurs in one encyclopedia. Topics are short but at least give you information on many ideas and information that current for the field of dinosaur study. Of the three listed this book is number one in my collection because it contains information about every dinosaur known as of 1997. This is probably the biggest number of questions I am asked.
