Census Hurdles – Microfilming Errors

When moving from one level of human interaction with a piece of information to the next, we introduce more and more potential for errors. I’ve already discussed some sources of errors such as language barriers, literacy, handwriting, and indexing errors. There is also the possibility of errors in microfilming.

If you are browsing images either online or on microfilm, you might want to pay attention to the page numbers. Were any pages skipped when microfilming the original census books? If there weren’t necessarily page numbers on every page, you can pay attention to dwelling and family numbers to be sure they are in sequential order and none were skipped from page to page.

I have been victim to those really dark or really faint microfilmed pages. Check out some of these beauties:

I’m not sure how we are really supposed to read these, let alone the indexers. Thankfully, there have been some really great advances in digitization and many of these dark and light images can be corrected.

Other oddities I have seen:

  • hands in the image
  • pages not completely turned
  • blurred images, as if the page was being turned while being filmed
  • other pieces of paper in the image, over the census

I’m sure everyone has a fun example of microfilming errors. I’m hoping over time, these errors are being fixed and improved. It just highlights the fact that no one is perfect, right down to the folks who run the photography equipment.
