Sample Images

Indexing Names

  • The indexed cards were usually filed in alphabetical order by surname.
  • In the Given Names and Surname fields, index only the name of the person who was naturalized. Do not index any other names that may appear on the form, such as the names of witnesses, judges, or family members.
  • Titles and terms are not indexed in name fields.
  • If alias names were included on a naturalization card or if an individual’s name was listed with various spellings on the card, include all variants, separating each with the word Or. For example, if a name was written as "Georgios (George), George Broski, George Browzowski, or George Brzozowski," you would index the name fields as follows:
    • Given Names: Georgios Or George
    • Surname: Broski Or Browzowski Or Brzozowski

Indexing Dates and Ages

  • If the age of an individual was recorded but not a birth year, do not index the age in the Birth Year field, and do not calculate a birth year based on the age.
  • If a birth year was recorded for an individual but not the age, do not calculate the age based on the birth year and the event year.

Diacritics and Other Characters

  • If the name of a person or locality was written with a character not on your keyboard, such as the ò in Nicolò, please insert the character by clicking on the Enter special international characters icon (which is a square with an "ñ" in it) and selecting the character you want to insert, or:
    1. On the menu bar, click Edit.
    2. Click International Letters.
    3. Click the letter you want to insert.

Corrected or Crossed-Out Information

  • When information was crossed out and then replaced, type the new data in the appropriate fields.
  • When information was crossed out, was not replaced, and can be read, type the crossed-out information.
  • If information was not crossed out but was replaced or was added to, type the most complete version of the record.
  • When the information was crossed out, was not replaced, and cannot be read, mark the field as unreadable by pressing Ctrl+U.
  • When every entry on a record cannot be read, mark the entire record as unreadable by pressing Ctrl+Shift+U.

  • Highlights are not available for this project. You may use the ruler instead to follow a record across an image.
  • If you choose to use the ruler, please be aware that the ruler is not anchored to the indexing screen and does not automatically move as you move to a new entry. To use the ruler:
    • On the menu bar, click View.
    • Select Show Ruler.
