 In 2019, Eduard Petiška and Bedřich Moldan proposed ‘Verifiability by respected sources’ as an indicator for assessing the quality of Wikipedia articles at the higher education level and conducted an analysis of the most frequently visited articles in the category of Environment on Wikipedia.Results show that these articles contain many unreferenced statements and their usage at the higher education level could be problematic.Some academic journals do refer to Wikipedia articles, but are not elevating it to the same level as traditional references.
