A few sites do not load properly in a frame, I have therefore targeted them into a new window. Those sites are marked with ++
Sites which are highly recommended are marked with ****
though there are many more excellent sites which I have not marked due to time constraints evaluating each one.
The highlighter only uses one color each for words or for phrases and is
accumulative, i.e. if you make more than one search all words will remain
highlighted with the one colour, and phrases with the other. To clear, click
the back button and start again.
