Thank you Rodrigo, our Library of Congress colleague who kindly agreed to share his OCR method here on History Hub for volunteers to use if they like. This process will be helpful for getting text for printed documents, rather than handwritten ones. It can really save time when you're dealing with newsprint, though as Rodrigo says and demonstrates in his examples, there are times when OCR doesn't work so well--always read through the automatically generated text to check that it accurately represents the original (including any punctuation, accents or spelling, regardless of whether this is "correct" by modern standards). You can also get images of each document by clicking on the "view on loc.gov" button in the transcription interface.
Please preserve the original line breaks as you would if you were transcribing. Make sure that words broken over two lines such as kit-
are transcribed as a whole word on the first line, so "kitten", in this example.
I have started using this OCR method and it is awesome. Thanks so much for sharing.
