US, Michigan—Port of Detroit Manifests, 1906–1954

Project Instructions

Multiple Dates per Record

  • Cards may include multiple dates.
  • Index the manifest date, which is usually written or typed at or near the top of the card.
  • If the card does not include a manifest date but has a landing or arrival date (usually at or near the bottom of the card), index the landing date instead.

Back of Manifest Cards

  • Only the front of manifest cards contains information to be indexed in this project.
  • If an image shows both the front and back of a manifest card, index the front only and ignore the back.
  • If an image shows the back of a manifest card only, mark the image as a No Extractable Data Image.

Records per Image

  • The data entry area is set at one record per image, and most images contain just one record (just one card).
  • On rare occasions, an image will show the front side of two cards. (Click here to see an example.) In this case, you will need to add entry lines to match the number of records on the image. To add entry lines:
    1. On the menu bar, click Tools.
    2. Click Records per Image.
    3. Click in the Number of records box, and type the number of records on the image.
    4. Click OK.
  • To help identify the number of records on an image:
    1. Click the Image Navigation tab in the bottom right corner of the screen.
    2. Click and drag the dark gray box with your mouse to move around to all areas of the image.

Names from Many Cultures

  • Names in this project may come from many cultures. If a diacritic or accent mark was used in writing a name on the record (such as the marks used in writing ò in Nicolò or à in Nicolàs), be sure to include the accent mark in indexing the name.
  • Be aware that names in the lookup list may not follow normal alphabetic rules.
  • If the name of a person or locality is written with a character not on your keyboard, such as the accented ò in Nicolò, please insert the character by doing the following:
    1. On the menu bar, click Edit.
    2. Click International Letters.
    3. Click on the letter you want to insert.


    1. On the menu bar above the data entry area, click the Enter special international characters icon (which is a square with an ñ in it).
    2. Click on the letter you want to insert.

Corrected or Crossed-Out Information

  • When information is crossed out and then replaced, type the new data in the appropriate fields.
  • When the information is crossed out, is not replaced, and can be read, type the crossed-out information.
  • If information is not crossed out but is replaced or has been added to, type the most complete version of the record.
  • When the information is crossed out, is not replaced, and cannot be read, mark the field as unreadable by pressing Ctrl+U.
  • When no entry on a record can be read, mark the entire record as unreadable by pressing Ctrl+Shift+U.

Duplicate Images

  • At times, an image in a batch is a duplicate of the previous image.
  • If you see a duplicate image, index the version of the image that is the easiest to read. It is acceptable to combine information from the duplicate record with the information from the one being indexed if it is easier to read some of the information on the duplicate.
  • Mark the other image as a duplicate by doing the following:
    1. Click the Header Data tab.
    2. Click in the Image Type field.
    3. Select Duplicate Image from the list.
    4. Click Yes on the warning message.
  • Finish indexing the rest of the images in the batch.
  • Some images may appear to be duplicates but aren't actually duplicates. Some records, for example, may contain information that is similar to the information on another image. Before you mark an image as a duplicate, make sure it is an exact duplicate of the previous image.
