Dear Matthias,

this will be the topic of my presentation at the Canadian Stata User
Group Meeting in Toronto in a couple of weeks:

"Data cleaning in Stata using internet search engines"

I will show how Google can be used to catch just the typos that
you describe.

The registration is still open until Oct. 16th.

Best regards,
     Sergiy Radyakin
