(3)More than 100 million people in Nigeria are not connected to the Internet. There are only a few networks that offer service and it is costly and unreliable. Now, a new project provides a resource for offline viewing at no cost.
    A non-profit organization called The WiderNet Project has developed the offline eGranary Digital Library. The service puts millions of digital documents, multimedia work and websites onto a server.(4)The information is then available to students, medical workers, and researchers at no cost, whether there is Internet or not. Users can access informative websites that eGranary updates every day such as Wikipedia, Khan Academy, Project Gutenberg, MIT OpenCourseWare, and MIT BLOSSOMS(which is Math and Science video lessons for high school students). Other resources on the service include university and medical publications, computer software, and educational games.
