Category:Articles with non-HTML file bare URLs for citations

This is a tracking category. It is used to build and maintain lists of pages—primarily for the sake of the lists themselves and their use in article and category maintenance. It is not part of the encyclopedia's categorization scheme. More information: This category is hidden on its member pages—unless the corresponding user preference is set. These categories are used to track, build and organize lists of pages needing "attention en masse" (for example, pages using deprecated syntax), or that may need to be edited at someone's earliest convenience. These categories also serve to aggregate members of several lists or sub-categories into a larger, more efficient list (discriminated by classifications).

This is a tracking category for Bare URL references to non-HTML files, which have been tagged with {{Bare URL non-HTML}}

These bare URL refs are tracked separately because tools such as Citation bot, Reflinks and reFill cannot extract metadata from non-HTML files, so the metadata such as title, author and publication date needs to be added manually.
