User:DexDor/Finding miscategorizations

This page contains links to a category intersection tool (Petscan) to check whether there are pages at some combinations of namespace and high level categories. For a table showing which combinations of namespace and category are valid see User:DexDor/NSCat. For more information about how pages become miscategorized and how to fix them see User:DexDor/FHL.

The table shown below (in which the rows roughly correspond to the columns of the NSCat table) includes links to a category intersection tool that can identify any pages at certain combinations of namespace and category.
