I found a blog that focuses on children's and YA books, and the blog-keeper had rated all the Newbery books for what grade level she thought was the entry level (ie, probably wouldn't be suitable for kids in lower grades), plus whether she especially liked the book or not. Of course I thought of your project! In fact, I mentioned it in comments. But in scrolling through the list, I saw Strawberry Girl, and I couldn't recall having read anything from you about it. (Here's the link (http://www.pragmaticmom.com/2011/09/newbery-award-winners-by-grade-appropriateness-from-hubspot/#comment-89816) to the entry.)
