An EGranary Digital Library caches educational resources via a local area network in order to reduce connectivity costs in Internet-scarce areas. Most eGranary subscribers do not have an Internet connection, but those who do can open resources up to 5,000 times faster from the eGranary Digital Library - wikipedia 
The eGranary Digital Library contains an off-line collection of approximately 30 million educational resources from more than 2,500 Web sites and hundreds of CD-ROMs and fits on a 4TB hard drive.
The eGranary Digital Library contains a built-in proxy server and search engine similar to the Internet, at a speed that is otherwise not usually available to them. The proxy server allows users' Web requests to "play-through" to the Internet if a connection is available.
The eGranary's interface includes a word search powered by Lucene and Solr, an online public access catalog powered by VuFind which contains over 60,000 records, and dozens of portals cooperatively developed with experts from around the world.
