I just returned from a workshop held by the PA Dept. of Education regarding Access PA. Access PA is a statewide database containing the holdings of almost all of the libraries in Pennsylvania. In addition, the website also features a wealth of reference material covering just about any topic you could possibly be seeking. I'm sure you've seen Power Library mentioned before on this blog, but I'm going to make a point of featuring some of the wonderful stuff being provided with more attention to specifics in future blog posts. And it is all absolutely free to use as long as you have a library card! Watch for my weekly Power Library Post starting Thursday.
