To get to these resources, visit the NC WiseOwl website at http://www.ncwiseowl.org/ . Click on Elementary School Zone. On the left menu, choose eBook collection, where you can search by category, author, title, etc.
Other great resources for reading books online are Storyline Online (the book is read by a celebrity on YouTube) and WeGiveBooks where the books you read also help various organizations receive books.
Check out our website for other great links for students! I will be writing a new post soon about our great databases resources for research and learning.
