There is a great deal of information about books on the Internet. Apart from the sites selling books, there are sites for authors and publishers, sites with book reviews written by children, and sites where parents can find helpful information. The following list, suggested by The Federation of Children's Book Groups, is a good place to start; several of the sites will have links to others.
"The chock full, eyes-peeled, independent children's book site..."
Book plates, book marks, book reviews, book shops...
"Everything you need to know about children's books and authors."
"Book reviews, news and interviews."
"Free Your Imagination: Books on the BBC. A major season of programmes focusing on literature on BBC TV and radio. "
"The children's book magazine online."
"Web-based literacy programme for boys."
"All the best books for children, young adults, parents, teachers and librarians, with reviews and ratings, games, stories and jokes."
