All of the "official language" opinions aside, I would think that for reasons of safety, such as a response from the fire department, electric company, etc., there should be a directory in English.
Additionally, for reasons of safety, if the workers/residents/etc. speak a language other than English, the second language should also appear on the directory.
I also would like to see penmanship taught in schools, not just typing. (Though computer-printed directories do make for a professional job.)
