I stumbled across this website when I was searching for an image of the Topsy and Tim birthday book to share with a friend…what an awesome resource! This free online catalog of themed picture book summaries and reviews is staffed (on a volunteer basis, I believe) by professionals ranging from a librarian to a psychotherapist who have compiled this collection of books to help children cope with or learn about different difficulties or new experiences they may encounter in their lives, like moving, allergies, bullying, and many more. Books are searchable by keyword or by preselected themes, and there is a way to submit reviews of the books featured or ideas for new books for inclusion on the site as well. As this project is UK-based, it appears that most of the books are of British origin, but I know that some of the books at least (such as those by Lucy Cousins and the Usborne First Experiences series) are readily available here in the United States as well. Although you can always do a web search for collections on specific themes since many blogs (like this one!) do periodic themed posts and reviews and issue-specific associations and support groups often include children’s book lists on their topic, I don’t currently know of an American equivalent of this broad coverage of “life’s challenges” for children, but anyone with any knowledge of something similar is welcome to share in the comments!
