How to proofread handwriting OCR: a practical checklist

Your handwritten page has become editable text. Before copying it into a report or filing it away, open the photograph alongside it. The question now is whether the transcription matches the page. A smooth sentence alone cannot answer that.

This checklist starts after recognition. If you still need to capture or convert your pages, start with the note digitization guide. You can do the checks below in any text editor, with the original on paper or on screen.

First, check that everything is there

Start with the photograph, not the transcription. Follow each paragraph on the page and find its counterpart in the text. Check the bottom edge, the margins and any continuation on the next page. With lists, compare the entries one by one. With columns, check which heading each value belongs to.

A missing phrase may leave a perfectly readable sentence behind. The University of Pennsylvania’s transcribing and proofreading guide specifically identifies omissions that preserve apparent meaning, and recommends checking against the original. Spell-checking alone will not recover an absent line.

Do not expect the same number of screen lines: wrapping changes with font and window width. Match the words and their order. For your own review, note the source page and paragraph when you pause so you can resume at the right place.

Read the details that change the meaning

Once the page is complete, compare the wording line by line. Give names, dates, numbers, units and negations a separate look. The examples below are invented exercises, not measured OCR results.

• “15 boxes” becomes “75 boxes”. Compare the first digit with other clear examples of 1 and 7 on the page.
• “Do not send” becomes “Do send”. Check the short words as carefully as the nouns.
• “Maren” becomes “Karen”. A familiar name is not proof of a correct reading. Look at the initial stroke.
• “1.5 m” becomes “15 m”. Check decimal marks and units separately from the digits.

Correct the occurrence you have checked. Before using “replace all”, inspect the other matches: the same output word may be correct elsewhere. After editing, reread the corrected phrase against the image to catch an accidental deletion or duplicated word.

Keep unresolved words visible

If a letter is unclear, compare it with the same writer’s clearer letters elsewhere. If the photograph is blurred and the original is available, take another picture. When neither resolves the reading, leave a visible marker instead of quietly choosing the word that sounds best.

For its archive transcriptions, the US National Archives recommends comparing letterforms and marking unreadable words with [illegible]. In your own working copy, explain your convention once. For example, use [illegible] in the text and put a possible reading in a separate review note. If you contribute to an archive project, follow its conventions instead.

Separate faithful transcription from editing

Decide whether you are preserving the wording or preparing a rewritten document. For a quotation, keep the wording you can verify on the page. For a polished report, make a separate edited copy after checking the transcription. That leaves a way to tell what the author wrote and what you changed.

Do the same with abbreviations: keep the source form in the faithful copy and put an expansion in your notes if it needs explanation. Our guide to old letters and family archives covers the broader task of preserving and organizing those originals.

Do I need to check words that are not flagged?

Yes, if you need a fully checked transcription. Encria underlines low-confidence words to help prioritize review. Those marks are review cues, not a guarantee that everything else is correct. A missing passage also needs a comparison with the source. For more background, read why handwriting OCR makes mistakes.

Before you share or reuse the text

1. Account for each source page, including margins and continuation lines.
2. Compare the text with the source, then recheck names, numbers, units and negations.
3. Search for your uncertainty markers and resolve them or leave them clearly explained.
4. Keep the source images and distinguish the checked transcription from any rewritten copy.

Start with one page in Encria if you want to try its correction flow, then use this checklist on the result. If you checked only selected details, label the document as partially reviewed. “Names and dates checked; remaining text unreviewed” tells the next reader more than “done”.
