Text correction home

When issues are prepared for display online, Optical Character Recognition (OCR) software is used to generate searchable text. OCR enables searching of large quantities of full-text data, but it is never 100% accurate. The level of accuracy depends on the print quality of the original issue, its condition at the time of microfilming, the level of detail captured by the microfilm scanner, and the quality of the OCR software. Issues with poor quality paper, small print, mixed fonts, multiple column layouts, or damaged pages may have poor OCR accuracy.

OCR text correction allows members of the public to help improve the searchability of this collection by correcting errors in the text of the digitized newspapers. Saving these corrections to the collection database improves the accuracy of the text, which enables better search results and a richer experience for all users.

We welcome new contributors to our OCR text correction community. Anyone can participate as long as they have created an account and logged in.

You can edit the automatically recognised text of the newspapers published before 1944. Corrections can be made only by users who have registered and logged in with their library username, ID-card or Mobile-ID.

To edit text, click on the left side of the viewer Correct this text. Choose a part you want to edit (e.g. an article). Now you can see the automatically recognised text on the left and you can edit it right there. The text can be edited row by row. The red box on the right helps you to follow the rows and see which text belongs to a certain row. When you have finished editing, click Save. NB! All saved changes will be immediately visible for all users. To quit, click Cancel, and all changes made since the last save will be cancelled.

You can continue editing by clicking Next on the following row or choosing another part on the right side of the viewer. To exit the editing mode, click Return to viewing mode. By clicking on the Save & exit, you can save and return to the viewing mode at the same time.

NB! Corrections have to be made exactly according to the way the text was published in the newspaper. You may not edit typographical errors or change punctuation marks and syntax or add your own comments and additions etc. Changes are being tracked by a moderator with the right to decline incorrect changes.
