In the final months of the IMPACT project in 2012, the KB worked together with one of the current digitisation projects Early Dutch Books Online (EDBO) to research various methods of improving OCR. EDBO is a combined effort between the KB and the university libraries of Leiden and Amsterdam to digitise 2 million pages of books from 1780 to 1800. After the digitisation process, they decided to hire a number of students to manually correct certain books. This provided the ideal opportunity for IMPACT to tag along and have some of these students work with a number of IMPACT tools.
