There seems to be increasing activity in digitizing naturalization records to make them available on line. Both Footnote.com and Ancestry.com have growing collections. It seems appropriate that those records would be getting attention since the naturalization event affected so many families.
You can check out the Ancestry collection at the Largo Public Library if you do not have a personal account.
The Pinellas Genealogy Society as has a class on finding and using naturalization records. It will be one of the breakout sessions at the annual seminar on 12 February (go to the PGS website for a registration form: http://www.rootsweb.ancestry.com/~flpgs/index.htm).
