The first one that you should check out is Turning The Paige. It’s a teens’ book review blog and is run by Paige Turner, who reads and reviews the books. You can search for books by genre, age level, series or grade through the categories in the sidebar. Turner has a rating system for the books reviewed which would not be foreign to students … A+ to F-. As the site was started only at the beginning of the year, there are not many reviews at the moment. But you might be interested in the “Top 10 Lists” category to find interesting reads.
As for the second resource, the name of the site is Ergo and is created and run by the State Library of Victoria, Australia. Information literacy for students and teachers at the high school / secondary school level is the focus of the site. It has great resources on research skills, essay writing skills and study skills. It has also many great resources for teachers as well. Although the site is quite Victoria- and Australia-centric in terms of the content, there are still many useful tips that anyone can use.
