text: OCR stands for Optical Character Recognition. OCR is a software tool that can extract print text from some documents.
  When will OCR work well?
  OCR does not work on handwriting. It only works for printed or typed text, meaning text created by a typewriter, printing press, or other mechanical means. OCR will do best on consistent and clear images of modern typefaces.
  Do I still need to review pages started with OCR?
  Yes! OCR is imperfect. It may not work well for some or all parts of a typed page, but it can be a great starting point. If you start a page with OCR, you should read the text closely before submitting. If you are reviewing a OCR-ed page, you also still need to review.
  We always want to use volunteer time effectively. When the Library of Congress digitizes a large group of printed pages, it will usually OCR them. The materials in By the People campaigns are not good candidates for applying OCR at scale, either because they are handwritten, a mixed collection of handwritten and print materials, or printed on paper or in a typeface that does not produce accurate OCR results. However, OCR can still be a useful starting point for some typed pages. Use it if it if you like it or skip it if you don’t!
  Clicking "Transcribe with OCR" will remove all existing transcription text and replace it with automatically generated text. We recommend saving existing text in a separate document if you may want to revisit it.
  Transcribing Clara Barton
  Nurse, educator, philanthropist, lecturer, and founder of the American Red Cross, Clara Barton (1821-1912) was one of the most prolific, active, and beloved women of her time.
  Her diaries, correspondence, and autobiographical materials provide deep insights into her life and work. Tens of thousands of pages of letterbooks include outgoing correspondence sent by Clara Barton and other Red Cross officials. Their pages chronicle major world disasters and conflicts and relief work efforts.
  Image filters can help!
  This campaign contains some difficult-to-read pages. Our viewer filters may help you read light, dark, or blurry pages by allowing you to adjust the brightness and contrast.
  Access the filters by clicking on the icon at the top of the image viewer (located between "flip horizontally" and "toggle full page").
  The filters build upon each other, so you can apply more than one at a time.
  Throughout this campaign you will see bleed-through, a common issue for thin pages. Ink seeps through the paper and appears as backward text.
  Bleed-through can make deciphering more difficult, but try your best. Ignore backward mirror image text and go to the previous page to view and transcribe it.
  The example of backwards text above (from a Clara Barton letterbook) is bleed-through and should not be transcribed.
  Transcribe with OCR
  This collection includes a lot of typed pages - you may want to use Optical Character Recognition (OCR) to get started. OCR is a tool that can extract print text from some documents.
  Try out the "Transcribe with OCR" button beneath the image viewer.
  Using this button will delete any existing transcription - please only apply it on typed pages.
