Americancentric, but: I would suggest that if you have a phone, programming the numbers for the local police, a good urgent care clinic in your area (a wiser choice than the ER, when possible), and your garage (especially if you don't have AAA). 911 is an important tool, but it is not always the best tool for the job, and the cost of updating your address book is essentially zero.

Oh, and perhaps the New York Public Library’s virtual reference service (depending on your long-distance plan).
