abbreviations - unique and unusual

Hi folks
Please look at the site http://www.gpoaccess.gov/executive.html.

1, A dyslexic such as myself, without a visual memory and pore visual 
recognition, will not be able to keep track of  abbreviations or find 
them in the page where they were referred to first. That why you need to 
expand each occurrence.

2, The definitions may well be unique in some cases - IE they are not 
restricted. However they are unusual.  I, the user, do not  know what 
they mean. That is why the word unusual is important.

We can define unusual -  say as being  usage were the expansion is more 
likely to be understood then the abbreviation. I think that is human 
testable in 99% of cases


All the bets
