In the early days of this wiki, Wikipedia forking was widely practised. That is, text was copied directly from Wikipedia in order to have some content on pages. As time went by, editors gradually adapted the text. In most cases, it's no longer possible to really see the commonality between the Wikipedia and Tardis versions of two articles, which makes the need for a visible template pointing back to Wikipedia unclear. In fact, Wikipedia's reuse guidelines don't actually require visible links at all.

As a community, we've moved on quite a bit from the early days. T:WIKIPEDIA makes clear that we don't allow Wikipedia forking on in-universe articles any more. Furthermore, the practise is now highly discouraged on out-of-universe pages.

This category exists to further reduce the visible links between Tardis and Wikipedia. It provides a link between articles that were marked, as of 22 October 2011, as having originated on Wikipedia. Thus, it replaces the link that would have been formed by the placement of the old Wikipedia template. The category is hidden so that it can be seen only by those who choose to enable hidden categories.

This category acts as partial attribution under the terms of wikipedia:wikipedia:Reusing Wikipedia content#Re-use of text under Creative Commons Attribute Share-Alike.

More precise links, which precisely match the requirements of WP:REUSE, are given in the page histories of each of these articles, and are edits performed by either user:CzechOut or user:CzechBot — most likely the latter.
