The quotations page offers great benefits to a great number of people. However, with a few small tweaks, it could open doors for even more people.
Have you considered including a link to any text-to-speech program to allow access to people who are visually impaired or who would like to listen rather than read the great works presented here? Microsoft has a text-to-speech program which may be compatible.
I would also suggest getting "Bobby Approved." This means that your site meets handicap certain accessibility guidelines.
Kudos to you on a fantastic site!!
