anyway to export the address book ot a text file?

My wife is blind and the address book with voiceover is a chore. it is easy to get around but to read the info under a card is a pain. I bought her a itouch for Christmas that will get around it better. but it would be good to have a simple txt or word doc type file on the desktop to look at.
over the years she has a txt file with the info I put it all in her address book but the file is faster. but it is a mess too.
