AP Language and Composition going without a text book

I'm teaching AP Lang. and Comp. this coming school year and I have elected not to order text books.  Does anyone teach this class, or any other class, without a text book and rely on digital resources?  If so, I would love some advice.  I teach in a school that is not a 1:1 computing institution  (yet).  I'm concerned with content management as well as student access to the materials.  Additionally, I would like to have all my students maintain blogs.  Any suggestions?

Thanks,
