Upon discovering a family document, you might notice several stamped or handwritten numbers on the edges or corners of the page. Or when looking at microfilm, there can be numbers stamped on the film below the document image. It’s hard to determine which one is the official page number. If an index provides you a page number, assume that any of the numbers appearing on the document might be the page number referenced in the index. For example, one indexer of a census may have used the stamped number, while another indexer may have noted the handwritten page number. Both would be correct because each number was used as a page number at some point in the document’s existence. When citing your own research, consider specifying which number you are using. You could say, “the hand written page number in the upper right corner” or “the stamped page number in the lower right corner,” or even more simply, "p. 34 (stamped)" or "p. 112 (penned)" in an effort to help future generations locate the document.
