I still haven't found what I'm looking for

While I would still like to see something that allows me to easily cross search Athens resources, I have been using a little Firefox addon for a while which is fantastically useful. Dr. Evil's 'Add to Search Bar' creates a search bar entry for pretty much any website that has a search facility. It works well with sites like BAILII and you can use it with Westlaw as well, but so far I haven't been able to get it to play with LexisNexis. A bit more tweaking perhaps.
