This was an interesting thing to read. Although the original link is not correct anymore.
I stumbled upon the following text at the bottom of the page:
John Wiley & Sons, Inc., Signs Agreement to Provide Titles to Bookshare
April 14, 2011 - Partnership Expands Bookshare Collection and Makes it Easier for People with Print Disabilities to Gain Access to a Wide Range of Titles.
Now I am a foreigner and I am reading it as follows.
I have no printer so I have a "Print Disability" so I am eligeble for gaining access to a wide range of titles from the publisher John Wiley & Sons, Inc.
Now I only have to figure out what is ment by "gaining access" and how to do it.
