When looking for Kids' Books Websites, I usually visit a few search engines and put in terms like children's books, kids' books, reviews of kids books, etc.
Today I did something brilliant. I borrowed links from my favorite KBWs. Let others do the work, say I - at least, some of the time.
Paper Tigers, a site that features books and authors from Southeast Asia and the Pacific Rim. Find authors, illustrators, outreach projects, interviews and book reviews on this colorful site.

The Book-A-Day Almanac is excellent! Every day, Anita Silvey, the blog's author does a lovely job of reviewing one children's book. Silvey also posts little notes about things that happen each day as well. This site is fun for readers of all ages.
