Every course can have a livebinder, where teachers can store online resources for students to access anywhere. LiveBinders is an electronic portfolio that allows its users to organize , bookmark, and share online content . It is a bookmarking tool that facilitates the organization of the information found online. Instead of saving the links of your favorite websites in other bookmarking services like Delicious for example, LiveBinders lets you organize your links into tabs accessible through instant click.
