For communities that lack adequate Internet connectivity—such as developing countries, rural areas, and prisons—offline information stores such as WiderNet's eGranary Digital Library (a collection of approximately thirty million educational resources from more than two thousand web sites and hundreds of CD-ROMs) provide offline access to information.[14] More recently, the Internet Archive announced an offline server project intended to provide access to material on inexpensive servers that can be updated using USB sticks and SD cards.[15]
