For those of you who are tired of having to lug heavy  textbooks around, and also happen to be gadget oriented,  reprieve may be just around the corner. Amazon plans to unveil on Wednesday a new  Kindle designed  especially for textbooks. The current Kindle e-reader has a  screen that is too small to display the photographs, charts  and graphs that are a prominent feature of many textbooks.  The new device should be more suitable for that, but how much more suitable is still under investigation.  In an  effort to determine how useful it might be as a textbook reader students at Case Western  University will be getting the new model with some textbooks  and course material pre-installed. Members of the Poly community who have no interest in a portable  electronic reader, but would still like to occasionally check references online instead of heading to the shelves and thumbing through the table of contents, there are several outstanding reference resources available to you through our online databases. Books24x7, Knovel, and SpringerLink  feature thousands of full text books you can read via any web browser.
