Sometimes the source information for IGI records includes a Batch number in addition to the microfilm number. The name and address of the person who submitted the form can be found on the microfilm by searching for the respective Batch. The steps for finding the right batch number are as follows:
- Search the microfilm for the Batch number as found on the IGI record. The batch numbers are generally in numerical order on the microfilm.
- The page number will be numerically filed within the batch. Sometimes the page number appears right after batch number on the form.
- The name and address of the person who submitted the information will be on the pages in the batch.
Remember that these records are from before 1991 and so the addresses you find may not be current.
