Andrew and co,
I have a big fat apology to make. It was actually the wikipedia page 
on Lambda Calculus where there are many occurrences of special symbols.
The Wikibook, as far as I've explored, is fully accessible. 
Nonetheless, I'd still be more than happy to make my contributions in 
any way I can. I am a beginner to functional programming and so I 
could play a useful role in ensuring the text takes nothing for 
granted with regard to the fundamental principles and beyond.

As a tip for anyone involved in writing and publishing scientific 
materials on the web, unless the maths is either written without any 
funny symbols or, better still, typeset in latex, it is not 
accessible to a screen-reader.

One small point about the Haskell source code is that the column 
indentations do not always appear in the screen reader 
browse  buffer. Of course, there are ways of getting around the issue 
and if the author of the Wikibook is interested we could discuss the 
details off list.
