i live in the condo of babel

a very good background resource for langauges is the ethnologue: languages of the world. if you need to know what languages (and i mean all) are spoken in a given country or where a given language is spoken (and i mean everywhere) this should be your first stop. while you might be somewhat surprised to know that there are 75 languages spoken in thailand, care to take a guess at how many are spoken in france, germany or the usa? and, of course, it has language information geographically.
