Now this is cool - KIWIX

An offline reader.  You download a text and KIWIX allows you to read it offline.
Major plus:  the text can be a website, a book, a video, a presentation. Anything.
The reader runs on most platforms and cell phones.  Free.
They also have a free server so you can host people (like a library)

They have content too.  Lots of content.  All of Project Gutenberg.  All of WikiPedia.
All of the TED Talks, all of Kahn Academy.  Just for starters.

Needless to say, I will be downloading a bunch of stuff over the next couple of weeks.
Professor Carrington to the white courtesy telephone please, Professor Carrington...
