Launch PetScan

PetScan (previously CatScan) is an external tool that searches an article category (and its subcategories) according to specified criteria to find articles, stubs, images, and categories. It can also be used for finding all articles that belong to two specified categories (the intersection). CatScan was developed by the German Wikipedian Duesentrieb and is run on Wikimedia Toolforge, as part of Wikimedia Foundation's cloud computing environment.[1]

  • finding articles for deletion sorting, example
  • finding articles for an educational project (class): search for stubs within a category corresponding to the class subject
  • finding certain articles with a certain template, e.g. featured articles containing the template {{citation needed}} (see box below)
