A [[MediaWiki]] extension called ProofreadPage was developed for Wikisource by developer ThomasV to improve the vetting of transcriptions by the project. This displays pages of scanned works side by side with the text relating to that page, allowing the text to be [[Proofreading|proofread]] and its accuracy later verified independently by any other editor.<ref name=Springer2010>{{cite book|title=Computers Helping People with Special Needs|chapter=Wiki, a New Way to Produce Accessible Documents|first1=Alex|last1=Bernier|first2=Dominique|last2=Burger|first3=Bruno|last3=Marmol|editor1-first=Klaus|editor1-last=Miesenberger|editor2-first=Joachim|editor2-last=Klaus|editor3-first=Wolfgang|editor3-last=Zagler|editor4-first=Arthur|editor4-last=Karshmer|publisher=Springer|year=2010|isbn=978-3-642-14096-9|pages=22–24}}</ref><ref>[[mw:Extension:Proofread Page|Proofread Page extension]] at MediaWiki.

The retouched images can then be converted into a [[Portable Document Format|PDF]] or [[DjVu]] file and uploaded to either Wikisource or [[Wikimedia Commons]].<ref name=Springer2010 />

This system assists editors in ensuring the accuracy of texts on Wikisource. The original page scans of completed works remain available to any user so that errors may be corrected later and readers may check texts against the originals. ProofreadPage also allows greater participation, since access to a physical copy of the original work is not necessary to be able to contribute to the project once images have been uploaded.{{Citation needed|date=October 2023}}
